Today on Twitter, Miley Cyrus shared something not so shocking: she drinks alcohol! At least, on special occasions. While getting ready to play bridesmaid at her friend Jen Talarico's wedding, 18-year-old Miley tweeted a revealing Twitpic of a pair of thong underwear and what looks to be a mimosa made with more champagne than orange juice. She didn't claim the glass as her own, but the glass (and the panties) say 'Bridesmaid,' so we came to our own conclusion. After all, it is a celebration! Also on Twitter, Big Boi and Rick Rozay let it be known that they are in charge, while Sara Bareilles chatted about toenail clippings in the airport (really) and Cody Simpson unleashed a new song from his forthcoming 'Coast to Coast' album.
