LOS ANGELES, April 15 (UPI) -- The audience erupted into ecstatic squeals of delight when Rita Ora ripped open Zac Efron's shirt at the MTV Movie Awards on Sunday night. But unfortunately for fans, he appears to be taken.
The 26-year-old former High School Musical star has started dating his 20-year-old Neighbors co-star Halston Sage, the pretty blonde he was photographed with at a basketball game earlier this month.
"They are definitely an item," a source told E! News. "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 he is so sweet. He's really good to her."
Efron went to rehab twice in March and April of last year, though it wasn't reported until months later.
Sage recently broke up with Glee star Chord Overstreet.
