Twilight’s Jamie Campbell Bower sure moves on quickly.

Less than two weeks after revealing he had split with Bonnie Wright, his fiancée of over a year, the 23-year-old has been caught getting close to his new co-star Lily Collins.

Bower and Collins, 23, were spotted walking hand in hand on Tuesday in Toronto, Canada, where they are set to start filming Mortal Instruments, based on the science fiction book series of the same name.

Now, the author of ‘Mortal Instruments’ has revealed that Collins and Bower were already “incredible together” a year ago.

Author Cassandra Clare says it was the chemistry between the pair in real life — even though Bower was engaged at the time — that landed them the role of on-screen lovers.

“He auditioned with Lily, and he and Lily had incredible chemistry that sort of blazed off the scene,” she said in an interview with MTV in June of last year.

“He was snarky funny where he needed to be snarky funny, and he was badass where he needed to be badass. And he and Lily were incredible together.”

They also rehearsed a kissing scene, Clare said.

According to the author, Collins — who has previously been romantically tied to Zac Efron — was certainly impressed with her possible co-star, campaigning to ensure her on-screen love interest was Bower.

“In fact, after all the auditions, because she’s done auditions with a bunch of different actors, she wrote to the head of the studio, Clint Culpepper of Screen Gems, and she was like, ‘It’s Jamie. It’s gotta be Jamie.’

“He told me that, this was before he had seen the audition, he told me that he wrote back and he was like, ‘He’s a rock star hipster kind of guy. Do you think he can be a badass warrior-dude, as well?’ And she wrote back and said, ‘That is Jace standing there. When you watch the audition, you’ll see what I see.’ ”

Ironically, Bower also met his ex-fiancé on set too.

After just six months of dating, the Sweeney Todd actor proposed to 21-year-old-old Wright, who he met on set of Harry Potter. The engaged couple had been living together in a London townhouse prior to the split.

Bower told the Daily Mail he was “heartbroken” last month but did not say when the pair had split.
