In today's Tweet Beat, Demi Lovato's announces her new tattoo by sharing a photo of herself and her new ink that reads "faith". (I can only assume she's referencing a certain ditty from 1987 featuring George Michael, his guitar, and his tight, acid-washed skinny jeans.) Plus, Adam McKay asks us to visualize Joe Biden in eyeliner, Adrienne Curry has some advice for the latest winner of Americas Next Top Model, and hey, Rocco: leave my sangria alone!
