Adam LambertAdam Lambert knows how to make a splash. With his debut album, 'For Your Entertainment,' out on Tuesday, "Glambert" has already got everybody talking over his sexually-charged 'American Music Awards' performance from Sunday. But for all his poise and obvious confidence, Lambert can still be blown away by the places his career takes him.

Take tomorrow for instance, when Lambert will be in New York to celebrate the album's release with a special appearance. "I'll be preparing for a talk show experience on 'David Letterman,' which is like totally surreal and amazing," he tells PopEater. "I'm going to be nervous as hell. Hopefully I'll get through it."
