Emma Watson has shot down rumours of her hooking up with her latest co-star Johnny Simmons, insisting that they are just friends. The duo who were said to be getting close on the set of their upcoming movie 'The Perks Of Being A Wallflower' were being photographed going for a run together in the Pennsylvania countryside.

However, despite the recent Internet reports that claimed the two are a couple, Watson's representative insisted that her client is just work colleague with Simmons, 25. This is complete fiction, the Daily Mail quoted the Harry Potter star's representative as saying.
