Lily Collins and Jamie Campbell Bower are unlikely to reconcile especially now that 'The Mortal Instruments: City of Bones' actress has been spotted spending much of her time with Zac Efron.

After the announcement that the filming of 'City of Ashes' will be temporarily delayed, Collins had no qualms going out with her former beau. Reports claim that the English-American actress briefly dated Efron in 2012. However, the two parted ways after a few weeks because of conflicts in their respective schedules.

Reports about their reunion started when they have been photographed coming out of a movie house recently. The two seemed oblivious to the fact that they were in a public place.  They walked towards the 'High School Musical' actor's car and immediately drove off to grab a quick bite.

While Efron previously denied that nothing romantic was going on between them, their Disneyland date seemed to contradict such statement.

The two clearly enjoyed being in the "happiest place on earth" that the 'Charlie St. Cloud' actor even held hands with the 24-year-old actress. One source tells E! Online that the two are merely hanging out as friends: "They were never really together, so you could say they split, but they were never an official couple. They hung out a bit, but it was super casual."

Insiders likewise claim that even if Efron and Collins do not have an official label for what's going on between them, the brunette beauty is one of the "good influences" for the heartthrob especially after his rehabilitation stint.
