X Æ A-12 Musk
Theo Wargo//Getty ImagesShortly after his son was born, Elon Musk tweeted that he and rapper Grimes chose the baby name X Æ A-12 Musk. Grimes later sorta-explained, via tweet, "X, the unknown variable •Æ, my elven spelling of Ai (love &/or Artificial intelligence)• A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent + (A=Archangel, my favorite song)." Then again, it's not legal to put numbers and diacritical marks on a birth certificate in California, so who knows what they're actually going to call the baby (or if they're just messing with us entirely).

Navy Rome
Colors are used as names all the time: Think Violet or Blue. But country singer Jason Aldean and his wife, Brittany, weren't exactly thinking of the color when they chose Navy for their daughter — they just liked the word Navy. "Having a name like Jason, it doesn't get much more common," Aldean, who also has a son named Memphis, tells Taste of Country. "I wanted [my kids] to have something a little cooler than that, but not like, crazy. I felt like both of their names were different. I don't know anybody else with those names."
Banks Violet
Initially, actress Hilary Duff and Matthew Koma thought they might use Violet as the first name. "We had one name picked out and then we swapped a week later and we haven’t discussed it since," she told People before the baby's 2018 birth. “The name that we first thought we were gonna use is going to be her middle name, so we’re like, ‘Let’s not stress over this anymore.’" Could Banks be a reference to her role in Agent Cody Banks?

Gravity Blue
While names inspired by nature are certainly on-trend, parents usually opt for fruit or flower names — not necessarily forces of physics. Yet the daughter of models Stormi Bree and Lucky Blue Smith, who was born in 2017, is fittingly named after the force that attracts two bodies of matter together.
Ode Mountain
Actress Jena Malone and then-boyfriend, photographer Ethan DeLorenzo, have kept mum about how they chose the name Ode Mountain for their now-5-year-old son — but it sounds like a solid, strong name.

Briar Rose
Any Disney fans in the house? Actors Rachel Bilson and Hayden Christensen are — enough to name their daughter, born in in 2014, after Sleeping Beauty. Christensen says, "We both love all things Disney, but Rachel especially was very keen on the name," ET Online reports.
Rosalind Arusha Arkadina Altalune Florence
No, this isn't a law firm — it's Uma Thurman's daughter's name. The A-list actress and her boyfriend, Arpad Busson, couldn't decide on a single name — so they went with five. "We couldn't quite agree on the name, so we call her Luna," Thurman told Jimmy Fallon after the July 2012 birth. "She's lucky that way."

Bronx Mowgli
In 2008, Fallout Boy bassist Pete Wentz gave a cryptic answer to why he and his then-wife, Ashlee Simpson, chose Bronx Mowgli as their son's name: "All these people have all these ideas on what it means ... It's kind of cool to leave the narrative what it is," the Daily News writes. Simpson went on to have another child with an unusual name — Jagger Snow — with actor/musician Evan Ross.
Kal-El Coppola
Jerod Harris//Getty ImagesComics fans know that Kal-El is Superman's Kryptonian name. So, how did Nic Cage's son, born in 2005, end up with the moniker? Cage says his then-wife, Alice Kim, "Wanted a unique name. Originally I thought of the name Kyle and then she said, ‘No, something more unusual but beautiful,’" People reports. "Then I remembered the old Superman comics and Kal-El was his original name on Krypton. So I wanted a name that stood for something good, was unique, and was American, and that’s all three."

Pilot Inspektor
Ari Perilstein/Getty Images for Hallmark Hall of FameActor Jason Lee did not pick this name because he wants his son to fly planes or, well, inspect things. Lee explains he named his boy (pictured here with sister Casper), born in September 2003, after a song on the band Grandaddy's album The Sophtware Slump: "The opening track, 'He's Simple, He's Dumb, He's the Pilot,' absolutely blew my mind when I first heard it. It was from this track that my wife, Beth, came up with the name Pilot for our son."
Banjo Patrick
Michael Tullberg/Getty ImagesSure, it's a stringed musical instrument, but it's also actor/director Rachel Griffiths's now-16-year-old son's name. And while the pick may seem odd to American ears, it has major meaning to the Australian-born Griffiths. Banjo Patterson was an aboriginal activist and an iconic Australian poet, best known for works like Waltzing Matilda and The Man From Snowy River.

Moxie CrimeFighter
Albert L. Ortega//Getty ImagesMagician Penn Jillette certainly gave his daughter, born in 2005, a name you'll never forget. Jillette says he chose the name because "Moxie is a name that was created by an American for the first national soft drink and then went on to mean chutzpah, and that's nice," he told the New York Times, adding. "It's only the losers named Dave that think having an unusual name is bad, and who cares what they think. They're named Dave." (Sorry, Daves of the world.)
Audio Science (2003)
Actress Shannyn Sossamon is a major defender of her 16-year-old son's name. (Her then-boyfriend, illustrator Dallas Clayton, read through the dictionary to find a good word instead of a name.) "Everyone likes to think I named my kid Audioscience, like that's his first name!" Sossamon told Details. "Science is his middle name. His name is Audio Clayton. Nobody calls anybody else by their first name and middle name. It drives me crazy! ... His name is actually Audio Clayton which is not that strange."

Tu Simone
In 2001, actor Rob Morrow named his daughter, Tu. Get it? Tomorrow. "If we have a son," Morrow told People, "I want to name him Bone, but I don't think [wife Debbon Ayer] will let me."
Harley Quinn
Batman villain Harley Quinn first appeared in an episode of Batman: The Animated Series in 1992. Seven years later, director Kevin Smith and his wife, Jennifer Schwalbach Smith, named their daughter after the harlequin-themed baddie. (She seems to be okay with it.) Now that Harley Quin is a major character in Suicide Squad and Birds of Prey, the name might catch on.

Poppy Honey Rosie, Daisy Boo Pamela, Petal Blossom Rainbow, Buddy Bear Maurice, and River Rocket Blue Dallas
No, these aren't a cast of really cute cartoon characters, playing in a meadow. They are the adorable children of British chef Jamie Oliver. (The kids range in ages from 17 to 3.) Oliver told People his wife, Jools, is in charge of the names. "We're probably quite lucky [Buddy] was a boy, really, because we were out of names [for] girls."
Reign Aston
Of course, we couldn't get through this list without including a few Kardashian names. While Kourtney's oldest children have relatively mild names (Mason and Penelope), the couple went wilder with a name for their now-4-year-old son. But Reign is a perfect name for a little boy whose father is, after all, Lord Scott Disick.
