Yup, it’s true: Miley is now alcohol legal aka 21 years old. Our lip-syncing kitten lover turned this historic age on Saturday and of course celebrated with her friends. She tweeted a pic of her cake (I’m guessing this one wasn’t gluten free, but you can make anything gluten free these days so….) with the caption, “the gayest birthday cake ever”. I have to agree girl and it looks delish!
