It seems like you can’t walk ten feet without seeing a nipple today. First, Lady Gaga all over the CFDA awards, then Khloe Kardashian’s six minute exposed nipple extravaganza on Fox and Friends this morning, during which she sat chatting with the hosts in a see through top and no bra. (Showing no embarrassment, Khloe later tweeted: “Thank God! I f*cking love nipples!!!!”)

In honor of these two class acts, we decided to do a nip slip retrospective. You may be surprised at some of the starlets who’ve let their girls come out unannounced. Yes, the usual suspects like Mischa and Paris are there, but so are Keira Knightley and Beyonce.
