They Call This Low Key?

Remember when Zac Efron said he was going to keep his 21st birthday low key?

Well, he didn't do a very good job as far as we're concerned.

He celebrated it at Pace in Hollywood alongside Ashley Tisdale, Jared Murillo, Aly and AJ, and Monique Coleman.

Also there, but not pictured below, Vanessa Hudgens, Michelle Trachtenburg, Brittany Snow, and Corbin Bleu.

It's weird that some of these kids got into the club... some, like Vanessa and AJ, aren't even 21 yet!
