GLAMBERT GUESTS AS "GLEE" BIG BRO'

GLAMBERT GUESTS AS "GLEE" BIG BRO'

Here’s an early warning blip that just showed up on our gaydar: Flamohboyant ADAM LAMBERT just signed for a special guest appearance on Fox TV smash hit “Glee” in April.

Producers made no secret of wanting the “American Idol” icon, and Adam just loved the idea – especially when he learned he’d be playing big-brother mentor to the character Kurt, who’s needing a little help in coming out of the closet.

(Wonder if Fox included a no-kissing/no-crotch-grabbing clause?)
