Zac Efron may not party like he once did, but that doesn't mean he can't have a little fun on his birthday.

The former High School Musical hottie rang in his 26th birthday with such famous faces as Robert Pattinson and Joe Jonas, according to Hollywood Life. That's a lot of eye candy at one party.

"Nice to see Zac Efron out celebrating his birthday with Joe Jonas, Robert Pattinson and more tonight :)" writes an onlooker on Twitter. Who knew they were all even friends?

They were all reportedly out at the Chateau Marmont in Hollywood for the celebration, which also included Joe's girlfriend, Blanda Eggenschwiler. Sources say that the celebration was rather low-key.

Zac completed two rehab stints earlier this year, so it's nice that his friends have been able to support him and wish him a happy birthday.

Hope it was a great one, Zac!
