It turns out that Zac Efron is really a romantic at heart.

The 27-year-old actor spoke with ET at Thursday's premiere of his new film We Are Your Friends in Hollywood, where he shared a small piece of his philosophy on love.

When asked if he believed in love at first sight, Zac said, "100 percent. It's a good thing to believe in."

That must be nice to hear for Zac's reported girlfriend Sami Miro!

Sami was recently seen with Zac in Hawaii while the star was filming Mike and Dave Need Wedding Dates, where they hung out on the beach and even went jogging.

According to Zach, it was jogging that helped him lose 10 pounds for his role in We Are Your Friends, in which he plays a DJ.

"The moment I signed up for the movie, I wasn't possessing the physicality of a DJ," Zac told ET, explaining his motivation for slimming down. "They sit behind their computers and they are not, I guess, built. So I just started running every day."

While 10 pounds might not sound like a lot, it's a big life change for an actor who's known for his formidable physique.

"I am very motivated when I go for it," Zach said.

We Are Your Friends hits theaters Aug. 28.
