The 'Twilight' Gang Monkeys Around at Concert

Life is far from all work and no play for the New Moon cast as they prepare to film the sequel to Twilight in Vancouver.

Twilight-ers Kellan Lutz, Taylor Lautner, Peter Facinelli, Nikki Reed, Kristen Stewart and Ashley Greene descended on the Backstage Lounge in Vancouver on Tuesday night to support fellow castmate Jackson Rathbone as his band, 100 Monkeys, played a gig.

But as Life & Style tells it, there was as much sweaty action going on in the audience as there was on stage.

"Taylor was preoccupied with a tall brunette," reports an anonymous concertgoer. "They were really into each other, dancing very close. She grabbed his crotch numerous times!"

Possibly inspired by that display, Reed showed a unique form of music appreciation. "Nikki was definitely into one of Jackson's bandmates," the mole continues. "While they were performing, she reached onstage and grazed his crotch with her hand. He quickly jumped back with a startled look on his face."

Also having an amorous old time was Greene, who took the opportunity to cozy up with a rumored new beau.

"Ashley was there with actor Ian Somerhalder, who appears to be her new boyfriend," says the eyewitness. "The two seemed really happy and kissed throughout the show!"

Somerhalder, it's worth noting, is set to star in The Vampire Diaries, the pilot for which has been picked up by the CW and will most likely run in the fall.

Hot vampire-on-vampire action? Now that's something to sink your teeth into.
