How old is Storm Brieanne Sixx? Born April 14, 1994, Nikki Sixx’s daughter is 32 in November 2026. Get her birthday, family background, and answers to related questions.
Why the Age of Storm Brieanne Sixx Matters to Readers
Every time a famous musician’s name trends, people start looking up his family. Nikki Sixx, the bassist and co-founder of Mötley Crüe, is one of rock’s most recognizable figures. His children have drawn steady curiosity over the years, and one of the most common searches is “Storm Brieanne Sixx age.”
Storm is the only one of the Sixx children who has stayed mostly out of public view, so reliable information about her is scattered across the web. Some pages contradict each other, and a few contain plain errors. Searches like “Storm Brieanne Sixx age” and “how old is Storm Brieanne Sixx” often lead to confusing results.
This guide gives a clear answer. It covers her birthday, how to calculate her current age, who her parents are, how she fits into the wider Sixx family, and why you should be careful with low-quality sources. It also addresses related searches such as “Decker Nilsson Sixx alive,” “Nikki Sixx children,” and “Courtney Sixx children.”
The Short Answer: How Old Is Storm Brieanne Sixx?
Storm Brieanne Sixx was born on April 14, 1994. Profiles of Nikki Sixx’s children give her birth date as April 14, 1994, and a biography entry for the musician lists the same date.
Today is November 12, 2026, so Storm Brieanne Sixx is 32 years old. She turns 33 on April 14, 2027.
That date is consistent across most of the sources I found. A few low-quality sites give different years or dates, which I cover in a later section.
Who Is Storm Brieanne Sixx?
Storm Brieanne Sixx is the daughter of Nikki Sixx and his first wife, Brandi Brandt. She is the middle child of their three children, born after Gunner Nicholas Sixx and before Decker Nilsson Sixx.
Unlike some celebrity children, Storm has not built a high-profile entertainment career. Coverage notes that she has largely stayed out of the spotlight and that little is known about her personal life. So the public record is thin: a birth date, her parents, and occasional glimpses her father has shared on social media.
Some websites claim she is a model, a reality TV personality, or a musician with her own band. Those claims usually appear on pages with no sourcing, and I could not verify them. Treat any detailed career story about her with skepticism.
Storm Brieanne Sixx’s Birthday and Zodiac Sign
April 14 falls under Aries, which runs roughly from March 21 to April 19. Readers who like astrology can read her as an Aries, though no reliable source has discussed her personality in those terms. Zodiac details are a common filler on celebrity-family pages and tell you nothing verified about her.
Her father has marked her birthdays publicly. In 2020, Nikki shared an Instagram photo from a father-daughter trip to Japan on her 26th birthday. That detail is useful for age verification because it matches the 1994 birth year: 26 in 2020 means born in 1994.
How to Calculate Her Age Yourself
You do not have to rely on any single website. Here is the method:
- Start with the birth year, 1994.
- Subtract it from the current year, 2026, which gives 32.
- Check whether her birthday (April 14) has already passed this year. If it has not, subtract one.
In November 2026 her birthday has passed, so she is 32. If you were reading this on April 1, 2026, the answer would have been 31.
The same method works for any public figure. You can also cross-check against milestone posts, such as the Japan trip birthday mentioned above.
Storm’s Parents: Nikki Sixx and Brandi Brandt
Nikki Sixx was born Frank Carlton Serafino Feranna Jr. on December 11, 1958, in San Jose, California. He co-founded Mötley Crüe in 1981 with drummer Tommy Lee and is the band’s primary songwriter.
Brandi Brandt is a model and former Playboy Playmate. She was married to Nikki from May 1989 to November 1996. Her own birthday is often listed as November 2, 1968, in Santa Clara, California, though that comes from a lower-quality biography site.
Their three children are:
- Gunner Nicholas Sixx, born January 25, 1991
- Storm Brieanne Sixx, born April 14, 1994
- Decker Nilsson Sixx, born May 23, 1995
Decker was only six months old when his parents divorced, so the three children grew up through their parents’ separation at very young ages.
Nikki Sixx’s Children: The Full Family
Searches for “Nikki Sixx children” usually want the complete list. Nikki has five children with three different partners:
| Child | Born | Mother |
| Gunner Nicholas | January 25, 1991 | Brandi Brandt |
| Storm Brieanne | April 14, 1994 | Brandi Brandt |
| Decker Nilsson | May 23, 1995 | Brandi Brandt |
| Frankie-Jean Mary | January 2, 2001 | Donna D’Errico |
| Ruby | July 27, 2019 | Courtney Bingham (Sixx) |
This table follows the commonly cited birth dates for each child. Storm is the second oldest and, at 32, sits roughly in the middle of an unusually wide age range. Her youngest sister, Ruby, is more than 25 years younger.
Many low-quality sites scramble this table, assigning the wrong mothers or swapping birth years. If a page lists Storm’s mother as anyone other than Brandi Brandt, that is a sign the page is unreliable.
Courtney Sixx’s Children
The phrase “Courtney Sixx children” refers to Nikki’s third wife, Courtney Bingham, whom he married in March 2014. Their daughter Ruby was born on July 27, 2019. Ruby is Courtney’s only child with Nikki, and she is Storm’s youngest half-sister.
Some pages claim Courtney is the mother of Decker or Frankie-Jean. That is incorrect. Decker’s mother is Brandi Brandt, and Frankie-Jean’s mother is Donna D’Errico. Because Courtney only entered the family in the 2010s, she is not the mother of anyone born in the 1990s or early 2000s.
Is Decker Nilsson Sixx Alive?
This is one of the most frequent related searches, and it deserves a clear answer: I found no credible reporting that Decker Nilsson Sixx has died. The query likely comes from curiosity about a low-profile family member, not from any news event.
What reliable coverage does say is that Decker graduated with honors from the University of Southern California in 2021. Another profile says he, like Storm, has chosen a lower-profile public life and focused on business interests.
Be careful with this query. “Is [name] alive” searches attract clickbait, and an absence of public updates is not evidence of anything. Like Storm, Decker keeps a private life, and if there were real news, major outlets would report it.
Related Names You May See: Lisa Marie Feranna and Jesse Evan Easterson
Two other names often appear next to searches for the Sixx family.
Lisa Marie Feranna is Nikki’s sister. She was born with Down syndrome and died around 2000. She is part of Nikki’s own family history, not Storm’s immediate family.
Jesse Evan Easterson is a name that appears in related searches, and I could not verify a clear connection to Storm or confirm details about the person. I would rather say that than invent a biography. If you plan to write about this name, check a reputable source first.
This is a good general rule: when a related-search name has no clear sourcing, leave it out or flag the uncertainty.
Nikki Sixx Net Worth and Why It Appears in These Searches
“Nikki Sixx net worth” shows up beside “Storm Brieanne Sixx age” because readers tend to explore a famous family as a whole. Nikki’s income comes from decades of Mötley Crüe albums and touring, his work with Sixx:A.M., his books, and his radio and photography work.
Published net worth figures vary widely from site to site and are estimates, not audited numbers. I would not quote a single figure as fact. Notably, the net worth of his children is even harder to know, and the figures posted for some of them online are speculative.
For Storm specifically, no credible source reports her finances. Anyone listing a precise net worth for her is guessing.
Why Sources Disagree About Storm’s Age
If you searched this question before, you may have seen conflicting answers. There are three common reasons:
Copied errors. Some sites scrape and rewrite each other’s content. One mistaken birth year spreads quickly. I found pages listing her birth as 2004 and another listing May 14, 1994, which conflict with the April 14, 1994 date that most sources and her father’s own birthday post support.
Outdated “age as of” lines. A page might say “Storm is 29 (as of 2023),” and readers assume that is current. Age statements go stale every year. Always check the date attached.
Mixed-up family members. Several low-quality pages attribute the wrong mother to Storm or confuse the children’s birth years. When a page gets other children wrong, its claim about Storm deserves less trust.
Practical tip: trust a birth date that appears across several independent profiles and matches an age milestone you can verify, such as “26th birthday in 2020.”
Respecting Privacy When Researching Public Families
Storm is a private adult who did not choose a public career. That matters when you write or search about her. Her birth date and parentage are widely published and fine to discuss. Her address, relationships, workplace, and daily life are not, and there is no good reason to look for them.
If you are a content creator covering the Sixx family, stick to information that is documented and already public: birth dates, parents, and anything the family has chosen to share. Avoid speculation about private matters, and do not repeat unverified claims about careers or health.
Conclusion
Storm Brieanne Sixx was born on April 14, 1994, which makes her 32 years old as of November 12, 2026. She is the daughter of Nikki Sixx and Brandi Brandt, the middle child of their three, and a sister to Gunner and Decker, with half-sisters Frankie-Jean and Ruby.
She has kept a low profile, so most of what circulates online beyond her birth date is thin or unverified. The best approach is to rely on consistent sources, calculate age yourself, and be skeptical of pages that scramble the family tree or invent a career.
