Vampy glam rocker Adam Lambert is a total “Twihard,” a pal of the American Idol glam rocker blabs in the June 29 issue of Star.

Adam’s friends say the trendsetting entertainer is a huge fan of Stephanie Meyer’s Twilight Saga film franchise.

“Adam owns multiple copies of the Twilight DVD. He keeps one at home, one with his laptop, and one at his parents’ house.”

And when he’s not watching the fangtastic vampire epic, he’s reenacting it.

Star writes: Adam and his boyfriend Drake LaBry, were overheard reciting lines from the film to each other while vacationing at the Bacara Resort & Spa in Santa Barbara.
