Efron and Sage were spotted having a good time at a basketball game recently


Zac Efron has a new girlfriend!

The ab-tastic actor is dating his Neighbors costar, Halston Sage, PEOPLE confirms.

“TK QUOTE” says a source. “TK QUOTE.”

On April 4, Efron, 26, and Sage, 20, stepped out together for the first time at the Staples Center. The new couple sat courtside laughing and cheering for the Los Angeles Lakers.

Sage, a former Nickelodeon actress who appears on the NBC series Crisis, recently broke up with Glee’s Chord Overstreet.

Meanwhile, Efron has been single for months, having previously stepped out with actress Lily Collins, 25. (Last October, they stepped out together to watch a movie in Hollywood and later that month, the two enjoyed a hand-holding date at Disneyland.)

Prior to that, Efron dated High School Musical costar Vanessa Hudgens for four years. They broke up in 2010.

Efron admits he’s jumped back in the dating game, having come to realize he’s not a serial dater.

“In real life I’m not as overwrought about dating,” he told InStyle in February. “That said, I’m not really great at dating either. I’m usually a one-woman guy, but these last four years I’ve been anything but. It’s been an extreme time, but it’s over now.”

As for the key to Efron’s heart? He likes a woman who is strong and happy.

“I think someone that’s creative and smart, self-confident,” he said at a press event for That Awkward Moment, on Oct. 15. “A nice smile, that’s a good thing to have.”
