He's rumored to be dating someone he was first romantically linked to in 2014. 

Zac Efron reportedly has a girlfriend — and unfortunately for High School Musical fans hoping for a Zanessa reunion (now that she's single), it's not Vanessa Hudgens.

Us Weekly reports the actor has moved onto a relationship with former co-star Halston Sage after having dated swimmer Sarah Bro for less than a year.

"The relationship just wasn’t working out," a source told Us about Efron and Bro. "She came back to L.A., and it never got going again."

Another source told the outlet Efron and Sage "are in a serious relationship and in love," and that they spent the holidays together. The two starred in Neighbors together, and were briefly romantically linked in April 2014, though those rumors died down by July of that year.

"She's really sweet. She's a sweetheart," he told Access Hollywood about Sage in 2014, though neither of them confirmed the rumors at the time.
