Robert Pattinson on Kristen Stewart break-up: 'S**t happens, you know?'

Robert Pattinson has opened up about Kristen Stewart reportedly cheating on him with director Rupert Sanders.

Speaking to Esquire magazine, Robert said: "S**t happens, you know? It's just young people...it's normal! And honestly, who gives a s**t?"

The actor also went on to explain how he felt protective of his ex-girlfriend when the allegations came to light.

"The hardest part was talking about it afterwards. Because when you talk about other people, it affects them in ways you can't predict. It's like that scene in 'Doubt,' where he's talking about how to take back gossip? They throw all those feathers from a pillow into the sky and you've got to go and collect all the feathers."

Robert and his Twilight co-star Kristen Stewart began dating when they met on set in 2008, but the relationship fell apart after allegations of Kristen cheating with Snow White and the Huntsman director Rupert Sanders came to light in 2012.
