Check out what Lily Collins said about her real-life boyfriend and Mortal Instruments: City of Bones co-star Jamie Campbell Bower in this new MTV interview!

In the clip, the 23-year-old actress had nothing but good things to say about Jamie.

“When he walked into the room for the audition he nailed it,” Lily recalled. “He didn’t have to try. He’s that perfect mixture between being this, like, mysterious Jace and also very endearing and funny, and he brings this wit and charm that only Jamie can bring.”

Lily also spoke about Jamie‘s stunts in the movie, saying, “He’s kicking ass doing flips, and it’s really impressive and the same with all the other cast members.”
