While that name sounds bizarre and deliberately very, well, rockstar, the hip couple actually chose the moniker for a more sentimental reason.
After Kingston and Zuma Nesta Rock, "Bowie Flynn" is actually a combination of Stefani and Rossdale's mothers' maiden names. (This is also good news to anyone who felt like attempting identity theft of the mega-loaded couple. Not that we endorse it, buddy -- that's on you.)
Still, all things considered, Rossdale and Stefani's tykes have pretty vanilla names compared to some other rockstar kids. Don't believe us? Get a load of this list. Seriously, these celeb baby names make "Blue Ivy" sound like "Jane Smith."
Erykah Badu is undoubtedly a creative genius, and when she and then-lover Andre of Outkast had a son, naming him "Seven Sirius" seemed pretty lowkey considering the sources. Not so much for her other two tykes, who were named Puma Sabti and Mars Merkaba.

David Bowie and then-wife Angie named their son Zowie Zowie Bowie later changed his name to Duncan Jones, probably because he was sick of hating himself and being mad at his parents.
Sounds like mom Toni Braxton is as good at naming her kids as she is at managing her checkbook
Oh, wait. She welcomed son Denim in 2001, followed by Diezel in 2003.

Thank goodness actress and DJ Shannyn Sossamon gave her kids -- Audio Science Clayton and Mortimer Sossamon -- weird names so she can still get occasional Google Alerts for being included in lists like this

Jonas Rocket Delonge, son of Blink- guitarist and singer Tom Delonge, has a pretty smart name. Because most of us want to sent the Jonas Brothers on a one-way trip into space.

Bob Geldof is just so creative he can't help but name his kids Fifi Trixibell, Peaches Honeyblossom and Little Pixie Geldof Maybe that was one of the factors that led to Peaches' long string of poor life decisions.

Spice Girl Geri Halliwell named her baby girl after two of her favorite things: bluebells and Madonna It could be worse. What if she was into tumbleweeds and Limp Bizkit? At least Bluebell Madonna is a pretty adorable tot.

Motley Crue guitarist Nikki Sixx and then-girlfriend Brandi Brandt apparently were into meteorology, X-Men and cheese Give the guy some credit: If you've read The Heroin Diaries, you'd know he's made far worse choices in his life than naming his daughter Storm Brieann Sixx.

Erstwhile My Chemical Romance singer Gerard Way and wife LynZ of Mindless Self Indulgence named their daughter Bandit Hopefully it's not prophetic, or else she won't be okay. (She promises.)

Ashlee Simpson and her Fall Out Boy bassist ex-husband named their son Bronx Mowgli Wentz It's unclear whether the New York City borough, the hard rock band, or the Yankees inspired "Bronx." As for Mowgli, well, who doesn't love The Jungle Book? (Though really, in that case, "Louie" would have worked just as well, if not as immediately recognizably.)
