Exes Zac Efron and Lily Collins went to the movies in Hollywood on Friday, Oct. 11, and had many wondering if they are rekindling their romance.

The High School Musical actor dressed down in jeans and white shirts with a gold key around his neck, looking healthy only a few months after a reported stint in rehab. Collins wore a cute safety pin design knitted black sweater, dark denim skinny jeans and short black boots. Her short hair was straightened and she paired her look with an oversized pink shoulder bag

They walked side by side outside the ArcLight Cinemas and it is unclear which film they saw, according to Mail Online. Several times Collins, 24, reportedly looked over at Efron, 25, and smiled. They then left the theater together in his car.

The two actors dated for several months in 2012 and were spotted on dates together before reportedly breaking up over the summer of that year. Efron's last serious girlfriend was his High School musical co-star, Vanessa Hudgens. They dated from 2006 to 2010.

Collins last dated Jamie Campbell Bower, her Mortal Instruments: City of Bones co-star. They were together for one year until they split in August. Before that she was linked to Chord Overstreet and Taylor Lautner.

Efron has two films in post-production: That Awkward Moment, co-starring Miles Teller, and Neighbors, co-starring Seth Rogen, Rose Byrne and Dave Franco. Collins recently completed the romantic comedy Love, Rosie with Suki Waterhouse.

A day earlier, on Oct. 10, Efron had his arms around his Hairspray co-star Brittany Snow during the Haunted Hayride Halloween event in Los Angeles after he had bought a caramel apple on a stick. Director Adam Shankman was with them as well as Dancing with the Stars professional dancer Derek Hough and others, making it a group night out.
