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.
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.'
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.
Joaquin Rafael Bottom was born in 1974 in San Juan, Puerto Rico. He is the third of five children, all with equally as interesting names, including River (1970--1993), Rain (1973), Liberty (1976), Summer (1978), and a half-sister named Jodean (1964).
After Joaquin's parents, John Lee and Arlyn Bottom, married in 1969, the couple joined the religious cult the Children of God and traveled around South America. But they soon became disenchanted with the cult and moved back to the U.S. in 1978, where they changed their last name to 'Phoenix' to symbolise 'new beginning.'
Around this same time, a young Joaquin began calling himself 'Leaf,' desiring to have a similar nature-related name like his siblings. In a past Jay Leno interview, Joaquin said he had originally called himself 'Antleaf' as a child.
Leaf would become the name he would use as a child actor until, at age 15, he changed it back to Joaquin.

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.
Born Caryn Elaine Johnson, this famous actress and 'The View' correspondent didn't become Whoopi Goldberg until, while working in a theatre in San Diego, friends noticed she had a bit of a flatulence problem and began calling her Whoopi after a whoopee cushion.
'If you get a little gassy, you've got to let it go,' Whoopi has said. 'So people used to say to me, 'You're like a whoopee cushion.' And that's where the name came from.'
It was Whoopi's mother who felt her daughter should take a Jewish-sounding last name to advance her Hollywood career. And thus Whoopi Goldberg was born.
According to a Salon article from 2000, Walken was originally named after actor Ronald Colman.

With Black Eyed Peas band mates named will.i.am, apl.de.ap and Taboo, the name Stacy Ferguson just wasn't going to cut it.

With his paternal grandparents originally immigrants from Spain and Ireland, Sheen wanted to take on a more American name. His children share the Sheen surname.
According to a 2003 'Inside the Actors Studio' interview, his father, Martin Sheen, revealed he took his name from CBS casting director Robert Dale Martin, who gave him his big break, and a Catholic televangelist, Fulton J. Sheen, whom he thought was a great actor. Unlike his son Charlie, Martin never legally changed his name.
Emilio Estevez (right), of course, kept his name.
The youngest nominee ever for a Screen Actors Guild Award, Hannah Dakota Fanning goes by her middle name professionally instead of her legal first name.

According to IMDB, Caine changed his name after advice from an agent.
In 2009, Caine explained re-naming himself after Humphrey Bogart's character in 'The Caine Mutiny' to NY Mag.
'Bogart was my hero, and even though he came from a sort of snobby, aristocratic family--he was a distant relation of Princess Diana--when I was a kid I thought he was a tough guy,' said Caine. 'Any person with my working-class background would be a villain or a comic cipher, usually badly played, and with a rotten accent. There weren't a lot of guys in England for me to look up to.'
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.
