STORMBREAKER star ALEX PETTYFER romanced his co-star Sarah Bolger on the set of the teenage spy movie, although their fling didn't continue once shooting had finished. Pettyfer, 16, and Bolger, 15, became friendly behind the backs of co-stars including Ewan McGregor and Mickey Rourke. Bolger says, "I had a massive crush (on Alex). We shared a few kisses, but I wish we could have been together."
