Washington: Speculations are rife that Zac Efron has a new girlfriend, and its none other than his ` Neighbors` co-star Halston Sage.

Reportedly, that the pair was seeing each other casually during the filming of their movie and ever since the 26-year-old actor went to rehab, they got a lot closer.

Her friends love him and he`s really good to her, added the insider.

Earlier this month, the duo was spotted cheering for the Los Angeles Lakers at the Staples Center, and Sage had called it quits with the `Glee` star Chord Overstreet, only less than a week after her photos with Efron at the basketball game surfaced.
