Zac Efron looked quite cozy with rumored new girlfriend and "Neighbors" co-star Halston Sage on Monday at the premiere of their raunchy new comedy.
The co-stars - who started dating while filming "Neighbors" - were very hands on while walking Monday night's red carpet.
"It was fun," Zac told Access Hollywood about working with Halston.
Since wrapping, the pair was spotted at a Lakers game earlier this month also looking quite cozy.

So what does the 26-year-old think of Halston?
"She's really sweet. She's a sweetheart," Zac said of the 20-year-old actress.
And in what may be the biggest clue as to whether they're dating or not, Zac asked Access, "Did you talk to her? What did she say about me?"
Halston didn't reveal much about Zac when she chatted with Access, as she's not ready to talk about her personal life.
"It was great, he's a really talented actor, so he made it easy," she said of working with the actor.
Access pressed, inquiring if she and Zac also had a good friendship off-screen.
"Everyone... We all stay in touch," she responded. "It's so good, that's why we're so excited to be here because we all got so close over filming."
"Neighbors," also starring Seth Rogen and Dave Franco, opens on May 9.
