"Robert Pattinson had an amazing impact on Kristen Stewart during the filming of Twilight."

Everyone knows that the two are really, really close friends and Kristen has just admitted that she has started copying Rob.

When she was asked by Empire who her favourite band were she said: “That’s so hard man, so defining, you know your favourite…

“I’m going to steal Rob’s, we all listened to the same music when we were doing the movie and he’s obsessed with Van Morrison.

“He’s like, he lives for that man and like so subsequently I’m caught up in that as well.”

We think it’s really cute that Kristen has started to like the same music as Rob."
