'Tis the season…for experimenting with throwback hairstyles. Miss Miley gave her pixie a rest and hit the KROQ Almost Acoustic Christmas party in LA on Saturday with a new 'do: a blunt blonde bob. We dig it—even if she's just wiggin' out. Gaga rocked the red carpet at the Capital FM Jingle Bell Ball in London, but it wasn't her Versace we were looking at…it was the white dreadlocks. Apparently, '90s hair is it right now—thank the ladies of Melrose Place and alternative rock videos, respectively.
