In an interview, the 28-year-old actor has opened up about his split with his 'Twilight' co-star, reported Ace Showbiz.
"It happens, you know?" the British actor said with a laugh when asked about his split with Stewart following her cheating scandal with director Rupert Sanders, who was married to Liberty Ross at the time.
"It's just young people... It's normal! And honestly, who cares?"
The actor, however, admits that facing questions about the affair was tough.
"It's like that scene in 'Doubt' (2008, in which Philip Seymour Hoffman plays a priest suspected of inappropriate behaviour), 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," Pattinson said.
