Zac Efron celebrated his 21st birthday party at Pace in Hollywood on Saturday.

HSM pals Vanessa Hudgens, Monique Coleman and Ashley Tisdale (with boyfriend Jared Murillo) were around to celebrate. Zac’s Hairspray friends Brittany Snow and Amanda Bynes also came out to celebrate.

Pals Aly & AJ Michalka and Michelle Trachtenberg also attended the big birthday bash. After Pace, they took the party to Chateau Marmont.

Looks like Zac received a lot of alcohol for his birthday–Ketel One Vodka, Jack Daniels Whiskey and Grey Goose Vodka.

On Tuesday, the cast of High School Musical 3 will dance their way onto the TRL studio to share what Senior Year is like. On Wednesday, don’t miss Zac on ABC’s Good Morning America. The HSM3 cast will also guest on CBS’s The Early Show on Friday.
