It's safe to say that Drake has been privy to quite a lot of onstage action, thanks to performances alongside Nicki Minaj's bottom and so on, but we think this is the first time he's had the pleasure of enjoying an onstage kiss with a fellow popstar. And who better to rub chins with than Madonna, the lady famed for sucking the life force from Britney, Christina, and Miley, among others. 
This happened after she sang Express Yourself to Drake at the festival a matter of hours ago. We'll leave the rest to Drake's reaction, although we will doff the cap to Madonna's subtle "get your hands off my hair" manoeuvre. She's all about nuance.
