Either Zac Efron's calendar is filled with friend-dates with female pals, or he's playing the field! (Hey, no judgments here.)

Just one day after the 25-year-old actor cuddled up with Pitch Perfect star Brittany Snow, he took in a movie with Mortal Instruments actress Lily Collins.

Photographers snapped pics of Zac and Lily leaving a Hollywood movie theater on October 11 — Zac looking laid-back in blue jeans and an unbuttoned white button-down with a key hanging by a string around his neck, and Lily wearing navy jeans and a black knit sweater embroidered with the image of a safety pin. (Check out one such snapshot at E! Online.)

Zac and Lily never confirmed that they had ever dated, but sources told E! Online that they had seen each other for three months in mid-2012. "They were never an official couple," a source told the site at the time. "They hung out a bit, but it was super casual."

The hunky High School Musical alum has been the subject of many headlines recently after news broke that he had completed a rehab stint this spring for alcohol dependency. His historical drama Parkland — based on the events following President John F.  Kennedy's assassination — is currently in theaters. He also just wrapped two comedies: Neighbors and That Awkward Moment.

Do you think romance is in the air again? And do you think Lily and Zac make a cute couple? Give us your take below.
