The Primetime Emmys will air September 21, but some celebs got their trophies early at the Creative Arts Emmys, which recognize technical and other achievements in the 2007-2008 season.

Silly Sarah Silverman celebrated her big win for Outstanding Original Music and Lyrics for her "I'm F'ing Matt Damon" spoof. She's usually spotted in pigtails, ratty jeans and a t-shirt, but Silverman kicked into glam high-gear with a '50s prom-inspired dress and heels.

Fellow funny winner Kathy Griffin let the press in on the craziest rumor she's heard about herself, saying, "Mario Lopez propositioned me for... how should I say... a night in heaven. And I said no, 'cause I never would."

Ashley Tisdale was among the red carpet starlets, sparkling in a sexy, sleeveless cream dress. But the Disney star wasn't sure who she was wearing, "Collette Dennigan ... I think that's how you say it."

Other big winners included "Sex and the City" star Cyntha Nixon for a guest spot on "Law & Order: Special Victims Unit," and AMC hit "Mad Men," Showtime's original series "Californication" and HBO's mini series, "John Adams."

The Creative Arts Emmys Air on E! this Saturday.
