Ron Artest's 'Metta World Peace' and More Odd Celebrity Name Changes

June 27, 2011 — -- Say goodbye to Ron Artest and hello to ... Metta World Peace.

The Los Angeles Lakers forward filed paperwork last week to change his name. Why? That's not exactly clear, but perhaps the once bombastic basketball brawler wants a new moniker to fit with the more relaxed attitude he's taken on in recent years.

Beyond the obvious implications of making "World Peace" part of your name, "Metta" means loving kindness and compassion in Buddhist culture.

Of course, plenty of celebrities have changed their names in a not so out-of-the-box fashion. Jennifer Aniston was born with a mouthful of a last name -- Anastasakis. (Her parents, John and Nancy, changed their family name to Aniston on the advice of the actress's godfather, actor Telly Savalas.) Jon Stewart was once Jonathan Stuart Leibowitz; Steven Tyler was born Steven Tallarico.

If Artest was trying to outdo some of the more outlandish celebrity name changers that have come before him, though, he's got some competition:

That plan didn't pan out. Earlier this year, he told ESPN he's giving up the whole thing and going back to Johnson. "I don't have a choice right now," he said. "I've done enough with the Ocho thing." For now, he's still officially Ochocinco.

Stefani Joanne Angelina Germanotta isn't the first Gaga. Slate found out that there was a Babylonian slave owner in the sixth century B.C. named Gaga and a Madame de Gaga from early 20th century France. The latest Gaga's name was actually inspired by an autocorrect error in a text message her former manager sent her.
