AnnaLynne McCord, is that you?

The 90210 star (and animal lover) revealed a dramatic new hair color on Twitter this week – with the help of a furry friend.

“I’m in LOVE!!!!!!” McCord Tweeted on Tuesday, along with a photo of herself leaning over a snoozing white puppy. Bearing a slight resemblance to Alyssa Milano, the former blonde displayed dark brown tresses while wearing a cozy cardigan.
