Heat up your Cheesy Blasters and open a bag of Sabor de Soledad, because NBC's 30 Rock is premiering is seventh -- and final -- season this Thursday.
Over the years, stars Tina Fey and Alec Baldwin harnessed their star-power and had a little help from their friends by casting them as minor characters on the show. Aside from the regular cast, over 100 individual celebs have made caemos on the critically-acclaimed comedy.
From music heavy hitters like Maroon 5's Adam Levine and Sheryl Crow to politicians Al Gore and Condoleezza Rice, almost everyone in Hollywood has poked their heads in the TGS With Tracy Jordan studio at one point during the show's past six seasons.
Seeing how 30 Rock is starting its long farewell to TV tonight, Celebuzz is taking a look back at the show's most memorable guest stars.
Which famous face has appeared on the show, and who's set to return?
Michael Sheen, who played Liz's "settling soulmate" and now ex-boyfriend in Season 5, will also make an appearance.
“I think it will be hard,” Fey told Entertainment Weekly of ending the series. “[But] I would love to get another TV show on the air someday.”
