Zac Efron and Halston Sage an Item! 'The Neighbors' Co-Stars Dating RUMORS

So many hearts are about to be broken.

Zac Efron is a no longer a single man. A source tells E! News that the actor has been dating his Neighbors co-star Halston Sage.

"They are definitely an item. They were seeing each other a bit during filming of their movie together and ever since he went to rehab they got a lot closer. Her friends love him and say his is so sweet. He's really good to her."

Rumors of the coupling started last week when the two were seen together at an L.A. Lakers game. The now couple looked extremely happy together smiling from ear to ear.

Sage has been previously linked to Glee star Chord Overstreet who decided to call it quits less than a week after the Efron-Sage pictures from the game were released. Before being with Overstreet, Sage was linked to James Maslow of Big Time Rush fane who is currently on this season of Dancing with the Stars.

Sage wasn't present at the MTV Movie Awards this Sunday but I'm sure she wishes she was. During the show Efron accepted the Best Shirtless Performance trophy and singer Rita Ora gave the audience a full on view of Zac's chiseled abs.

Efron later tweet at Rita Ora saying, "@RitaOra Thanks for such a bold move. I don't know if I could've done that on my own."
