21. Britney Spears
Britney Spears had two big things to celebrate this year — she became engaged to longtime love Jason Trawick and she negotiated her way into a job on the US version of The X Factor! She’s in the middle of traveling the US to find contestants for the program's second season.
As of July 2011, she was on a global tour promoting her most recent album, Femme Fatale. It was a lot of traveling, but she was still able to have fun with her sons, Sean Preston and Jayden James, between shows, thanks to beach and pool days in Long Island and Rio. Over the Summer, Britney showed how hot her and Jason's chemistry is by casting him as her love interest in her video for "Criminal." Britney was honored with a tribute at the 2011 MTV VMAs. At the show, she received the Michael Jackson Video Vanguard honor.
She also rang in her 30th year last December, and shortly after, ended her tour in Puerto Rico. In mid-December, Britney and Jason confirmed their plans to wed. It didn't take Britney long to show off the custom-designed Neil Lane sparkler.
