Adam Lambert has a busy weekend ahead of him — style lounges to visit (he's expected at the KIIS-FM Grammy Gift Lounge today), a red carpet to host on Sunday (for America's top-rated celebrity news show, "Entertainment Tonight," no less) –  so he may want to home in tonight's birthday celebration … or not.

"Idol's" poster boy for all things glam turns 28 years young today, and here's hoping it's a happy one!

In honor of this momentous occasion, let's watch Adam "Strut" his stuff on "The Ellen DeGeneres Show" earlier this week.
