(Cover) - EN Showbiz - Lily Collins reportedly wants to "get to know" her latest co-star.

The actress is appearing in The Mortal Instruments alongside Jamie Campbell Bower, who recently split from his Harry Potter fiance Bonnie Wright.

Lily and Jamie have been spotted hand in hand while out walking and are apparently becoming increasingly close.

"Jamie and Lily have spent a lot of time together. They're taking things slowly because he has only just come out of a long-term relationship, but as they'll be working together for the next few months, they're hoping to get to know each other better," a source told UK magazine Grazia.

Bonnie has moved out of the home she shared with Jamie, who popped the question after they'd been dating for six months. She is said to be finding it hard to come to terms with the break-up.

"It was Jamie who ended things," an insider said. "Bonnie thought that the relationship would be forever, but while Jamie was upset about it, he seems to have moved on a lot quicker than she has." (C) Cover Media
