Fergie of the Black Eyed Peas will be officially called Fergie. The 38-year-old American singer has filed a petition in court to have her first and last name legally changed from Stacy Ann Ferguson to Fergie Duhamel.

According to TMZ, Fergie wrote in the documents she filed in Los Angeles County Superior Court that she wants to change her name from the average-sounding Stacy Ann to her superstar identity Fergie in order to "conform to the first name which she is commonly and professionally known as, and has been for many years."

So that means no one has called Fergie "Stacy" in years, and she wants to keep it that way.

As for Duhamel, this one is a given. She is married to actor Josh Duhamel since January 2009 after five years of dating. And from the looks of it, they are still so madly in love.

The hearing for her petition is scheduled on August 16, and on which she would likely be officially called Fergie Duhamel.

The Black Eyed Peas singer isn't the only celebrity who has changed her name legally. While most artists and actors only use screen names and retain their birth names, these stars opted to have the government officially recognise their new name.

Destiny Hope Cyrus was given the nickname of Miley when she was just a baby because, according to her parents, she was a "smiley" baby. In 2008 at the age of 15, she legally changed her name to Miley Cyrus, which was what everyone knew her by then anyway.

It's no secret that Nicole Richie is the adopted daughter of music superstar Lionel Richie. She was Nicole Camille Escovedo before she was entrusted into Lionel's care, but she was given her new last name at the age of nine.

Tom Cruise was Thomas Cruise Mapother IV, but he legally changed his name and dropped the Mapother. According to some reports, he changed his name because he didn't want to honour his father who gave him and his siblings rough childhood.

Angelina Jolie wasn't just Angelina Jolie when she was born. When her famous parents (actors Jon Voight and Marcheline Bertrand) divorced when she was young, she was Angelina Jolie Voight before she hit stardom herself. She was understandably closer to her mother, though, who abandoned her own career to raise her and her older brother James Haven.

In July 2002, she filed petition to have her surname legally dropped from her name.

And of course, who can forget Metta World Peace? Even non-NBA fans know that the former Los Angeles Lakers player was also formerly known as Ron Artest before the court approved his name change petition in September 2011. FYI, Metta - his first name - means loving and kindness toward all.

"Changing my name was meant to inspire and bring youth together all around the world," the baller whose last name is now World Peace said in a statement after his official name change said.
