Cheyenne Jackson & Vanessa Bayer to Guest Star on Will & Grace

Just when we thought Will & Grace couldn't possibly get any gayer, they've said "hold my martini" and announced that Cheyenne Jackson and Vanessa Bayer will guest star on an upcoming episode. Bayer, who left Saturday Night Live last season, and Jackson, who is a regular on American Horror Story, are set to join the cast soon, but no character or episodes details have been announced just yet.

This isn't the first time Will and Grace have lured in star-studded guests. The iconic series counts Jane Lynch, Ben Platt, Andrew Rannells, Nick Offerman, Minnie Driver, Michael Angarano, Harry Connick Jr. Molly Shannon, Leslie Jordan, and even Jennifer Lopez as guests. Jenny from the Block, by the way, is going to pull double duty--appearing as herself and her Shades of Blue character Harlee.
