Just call it Zac Efron & Friends.

Zac was in director-producer Adam Shankman's backyard the other day in Los Angeles, shooting a video for FunnyorDie.com.

Who did the guys enlist to help them out?

Shankman, a producer of the Efron's 17 Again and director of Hairspray, codirected the bit that features Vanessa Hudgens, Queen Latifah, Lance Bass, Carmen Electra, Lance Bass, Brody Jenner, Joel Madden, Nicole Richie and former MADtv crackup Nicole Sullivan.

Details are under wraps, but I've been told the video is tied to 17 Again. Sullivan, who is pregnant in real-life, plays a "white trash girl" and a Rolls Royce that Latifah drives in the video actually belongs to Shankman, according to a source.

While official photos from the shoot won't be released for a day or two (video should post sometime next week), you can see shirtless shots of Zac from the shoot over at my blogging pal Just Jared.

Thanks, J.J.!
