Adam Levine dyes hair platinum blonde

Adam Levine stole the show on Monday night's episode of The Voice, showing off platinum blonde hair.

The normally brunette singer, who was named People magazine's Sexiest Man last November, debuted the new look on Twitter before the show, posting a picture of himself posing with girlfriend Behati Prinsloo.

"Apocalypse prep course complete," he captioned the snap of the pair pulling serious expressions.



"There are so many things to talk about," Adam said when asked by E! about his new hairstyle.

"I didn't know anybody would be so fixated on this. I wanted to do something crazy. I don't know why I did it. I really couldn't tell you logically there was a reason."

He seemed to have some regrets over his new look. "I just wanted to do it and honestly, it's so much of a headache now I might want to shave my head or something."

His Victoria's Secret girlfriend, however, is a fan of the new 'do. "She loves it," he said. "She loves the hair."

The singer, 34, is engaged to Namibian beauty Behati after popping the question to her in Los Angeles last year.

His representative confirmed the happy news to People, saying, “Adam Levine and his girlfriend Behati Prinsloo are excited to announce they are engaged to be married.”

The couple began dating in May 2012, shortly after The Voice judge split from swimsuit model Anne Vyalitsyna after two years of dating.
