Demi Lovato goes blonde and has airport security problems

Singer and "X Factor" judge Demi Lovato debuted her new blonde hair at a Washington, D.C. event. It's a big change from her most recent brunette color, but far more tame than previous choices. Lovato attended the Substance Abuse and Mental Health Services Administration event, where she received an award.

While the old adage says that blondes have more fun, Lovato's return to the hair color hasn't been without a few problems. She tweeted May 6 that she had some travel issues, writing, "Almost didn't make it through airport security!! I look SO different from my driver's license!! Hahaha #blondehairdon'tcare"

The change in hair colors comes shortly after Lovato released all of the songs from her next album, "Demi," online. Though the album is due in stores May 14, it's available for free through her YouTube channel.
