Guest judges on the upcoming third season of RuPaul's Drag Race include Fantasia, Carmen Electra, Margaret Cho and Johnny Weir.

Before its Monday, January 24 premiere, all-gay cabler Logo will air the show's first-ever casting special.

RuPaul unleashed his first search for America's next superstar drag queen two years ago. After crowning two queens, and upping the number of contestants from 9 to 12, America's first drag queen superstar is ready for a third go-around.

Contestants on the reality show face a barrage of fashion-related and talent challenges in their quest to win a prize package that includes a headlining spot on Logo's Drag Race Tour, a lifetime supply of Kryolan Professional Make-up and a cash prize of $75,000.

Also appearing this season to judge the drag queens will be singer LaToya Jackson, talk show host Sharon Osbourne, Mike Ruiz, celebrity photographer and star of Logo's The A-List: New York, Chloe Sevigny, star of HBO's Big Love, fashion model Cheryl Tiegs, comedian Lily Tomlin and actress Vanessa Williams.
