We just can't get enough ... of Zac Efron!

Taking selfies and snapping every pic they could get, Zac's female fans went crazy for him at the premiere of his new comedy Neighbors last night in Westwood, Calif. And we can't blame them; he really cleans up well!

Outfitted in a sleek grey suit, the 26-year-old hottie was geared up for the throng of ladies hanging on his every move, taking photos with a bevy of onlookers. But the High School Musical star didn't have all the attention -- Dave Franco stole some major hearts last night while on the red carpet. Swoon!

We're pretty sure Seth Rogen also walked the carpet (we have the photos to prove it), but we aren't sure how much we really noticed or cared after our Efron-induced coma.

The film follows a young couple with a newborn baby (played by Rogen and Rose Byrne), who face some major difficulties when they are realize they are living next to a wild fraternity house with some unruly frat boys (Efron and Franco).

Neighbors moves into theaters on May 9.
