It's good to be a wolf -- just ask the men of the "New Moon" wolf pack.

"We come in, it's a party," Chaske Spencer told Access Hollywood's Shaun Robinson at the Los Angeles junket for the "Twilight" sequel.

"Vampires have that serious demeanor to them - when we come on set, that's when the party starts," Bronson Pelletier seconded.

The group certainly brought the party to their Access interview, laughing it up and arguing over who has the best six-pack of the bunch.

The frequently shirtless stars said they worked out for 90 minutes a day for the beefed-up torsos they show off in the film.

But to hear them tell it, the wolves that work out together, stay together.

"We had a wolf training camp," Alex Meraz explained. "It really helped us bond."

The wolf pack roars into action on November 20, when "New Moon" arrives in theaters.
