If you're waiting for an Emma Watson nipple slip, you'll have to wait a while longer, but in the mean time, we've got the next best thing: An Emma Watson bra slip. Here's Emma after having lunch (or possibly coffee) with a friend of hers (a very cute friend, I might add), and, well, it looks like another friend decided to come out and play. I'm referring to Emma breast, of course. Thanks to a low cut top, and some intrepid photography skills, what we have here is a totally juvenile, yet sexy as hell candid moment immortalised for prosperity.
Update: Emma's super-cute friend is actress Kaya Scodelario who can be seen in the series Skins on the channel E4. Also, I should have totally titled this post "Emma Watson's Bra Plays Peek-a-Boob." Oh well.
