Plenty of Hollywood's biggest names don't go by their birth names-Demi Moore, Tina Fey, Mila Kunis, and Dakota Fanning.
However, you probably don't know how the celebrities ended up with their current monikers.
Some are simple-Nicolas Cage, nephew of Francis Ford Coppola, changed his last name to make a name for himself without the worries of Hollywood nepotism.
Others, like Michael Caine and Martin Sheen are more inspired. And then there's Whoopi Goldberg, whose name was Caryn Johnson until friends noticed her flatulence problem.
Demi Moore - Demetria Gene Guynes
Moore kept the last name of her first husband Freddy Moore after they divorced in 1984.
Daughter Tallulah also legally changed her name to Lula. Father Bruce Willis first broke the news in 2007 on "The Late Show with David Letterman."
"She wanted me to mention here on the big show that she's legally changing her name from Talullah to Lula, just Lula," said Willis. "She doesn't like her name."
Reese Witherspoon - Laura Jeanne
The "Sweet Home Alabama" actress traded her first and middle name in for her mother's maiden name, "Reese."
Bono - Paul David Hewson
The U2 frontman and humanitarian we all know as Bono wasn't actually born with just one name. Before he became world famous, the Irish musician was known by the name Paul David Hewson. But his wife still reminds Bono of his roots, going by the name Ali Hewson.
The name Bono was originally a nickname, short for "Bono Vox" meaning "good voice" in Latin, said to be given by his friend Gavin Friday.
Ludacris - Christopher Brian Bridges
The rapper has said the stage name explains his split personality.
"The nickname is something I made up," said Ludacris. "Part of me is calm, cool, and collective (sic), while the other side is just beyond crazy."
Before becoming a rapper, Ludacris was known as "Chris Luva Luva" on Atlanta's Hot 97.
Katy Perry - Kathryn (Katy) Hudson
Before she was a chart-topping singer, Perry was producing Christian music, under her birth name, Kathryn Hudson. She released gospel record Katy Hudson under the former label Red Hill Records before adopting her mother's maiden name to avoid confusion with this actress Kate Hudson.
Natalie Portman - Natalie Herschlag
Oscar-winning actress Natalie Herschlag is better known by her stage name, Natalie Portman.
After being born in Jerusalem, Israel, in 1981 to an Israeli gynecologist father named Avner Hershlag and American mother named Shelley Stevens (her mother's family changed their last name from "Edelstein" to "Stevens" when arriving in the U.S. from Russia and Austria), Portman now holds dual American and Israeli citizenship.
BRING UP THE TOPIC WITH KRISTEN STEWART, BUT THEN CHAT ABOUT EMOTIONAL EATING IN GENERAL (WHAT DO YOU TWO EAT WHEN YOU'RE SAD/DEPRESSED....DO YOU THINK IT'S OKAY TO DO....ETC.....)
While most of us can't relate to exactly what Kristen Stewart is going through right now--big cheating scandal, photo splashed on newspapers everywhere, millions of emotional fans, hot boyfriend hitting the road--I think at least a few of us can relate to how she's dealing with it...
According to Radar, Kristen is staying with a producer friend and "hasn't showered or changed or washed her hair in several days," "crying nonstop," and is "laying around in her T-shirt and shorts and eating ice cream."
With the exception of the producer pal bit, this sounds like pretty familiar territory to me... you? So many of us fall into a pattern of emotional eating even when we're dealing with basic day-to-day kinds of things (a stressful exam, a meeting gone wrong, an argument with a friend). Throw in something big like a breakup and the comfort food option feels like the only food option.
I've gone the ice cream route when super-upset before (New York Super Fudge Chunk, how you doin'?) but my go-to food "friend" during times of extreme emotion is queso. I could probably live solely on melty cheese while waiting for my heart to mend.
Plastic Surgery gone wrong
Most people in Hollywood-arguably the most image-conscious place on the planet-have reportedly had some nips and tucks. Even icons like Marilyn Monroe reportedly had a little work done.
But some stars have taken going under the knife way to the extreme and the results aren't pretty.
These 17 celebrities paid up to $1 million dollars for puffy lips and stretched-out faces. We found some compilation videos on YouTube that showcase the worst of the worst.
There's one model who's so puffy from Botox you'll barely recognize her. Plus, a rock star who barely looks human.
Former Playboy playmate Shauna Sand's lip injections have totally changed the appearance of her face.
Former beauty queen and television presenter Bruna Felisberto reportedly had a nose job and cheek implants.
Reality star Heidi Montag, 25, had 10 procedures in one day, including a facelift and nose job. She now says she regrets the procedures.
Television actress Nikki Cox was reported to undergo cheek and lip implants at just 34-years-old.
1 Sweater, 5 Ways! See How Glamour Editors Are Wearing L.L. Bean's Cozy Fisherman Sweater
It was pretty much the best day ever when L.L. Bean sent the fashion team this fisherman sweater as a gift. Naturally, we all wore them to the office the very next day.
Even weirder, we all sit together in the office (which, btw, is constantly freezing, hence sweater-dressing in August). Talk about a quintuple take! L.L. Bean Cotton Fisherman Sweater, $99, llbean.com Even though we all started with the same foundation, each of us styled the sweater in a totally unique way that reflected our personal style.
Market editor Becky Malinsky styled hers with a matching pair of 7 For All Mankind white jeans. "I love wearing different shades of the same color," Becky said of her ensemble. "Wearing two similar, but not exactly the same shades can make any outfit look polished-even when you're just wearing a sweater and jeans!".
"I really love the combination of a tomboyish sweater with a mini skirt," said market assistant Mia Solkin of her super-cute DIY (!!) skirt and Cos sandals, "but honestly, I couldn't think of an outfit that I wouldn't wear this sweater with!".
How cool does senior accessories editor Maria Duenas Jacobs look in her Rebecca Taylor skirt and Prada shoes with the sweater? "I like the combination of a chunky knit with girly florals," Maria said, "and I love how cozy the sweater is! It's an instant classic!".
Lauren Tardanico Vreeland wore her sweater with a pair of cool leather-like Zara pants (which we're all now on the hunt for). "They're a coated denim that looks like leather, so the preppy sweater toned down their toughness a bit.", said Lauren.
Finally, I wore mine with a Proenza Schouler geometric-print skirt and an American Apparel neon cap (I'm trying to grow out my hair...so not cute). This sweater has officially replaced the white tank as my wear-with-everything neutral. There's literally nothing in my closet I wouldn't wear it with, from overalls to sequined trousers.
How would you wear this sweater? Which of these looks is your fave?
