Robert Pattinson missed out on a night of partying with his New Moon co-stars on Tuesday.

The British heartthrob was absent as Kristen Stewart, Taylor Lautner and pretty much all of the cast watched their co-star Jackson Rathbone ( who plays Jasper in the vampire series) sing with his band 100 Monkeys.

Alongside Nikki Reed, Ashley Greene, Kellan Lutz, and Peter Facinelli, Kristen and Taylor rocked out at the front of the crowd in support of their pal.

Taylor appeared to be enjoying the company of a mystery brunette who had her arm planted firmly around his shoulder for much of the night.

The cast looked closer than ever as they emerged from the Backstage Lounge in Granville Island - a shopping district in Vancouver.

And the look of love was in certainly in Ashley's eyes as she left hand-in-hand with new boyfriend, Lost star Ian Somerhalder.
