Hollywood's latest 'it girl' Emma Stone will make a cameo in an upcoming episode of 30 Rock, along with Andy Samberg and Nick Cannon, series creator Tina Fey has confirmed.

In an episode due to air at the end of the month in the States, Jenna (Jane Krakowski) and the aforementioned guest stars appear in "a movie from the producers of Valentine's Day and New Year's Eve called Martin Luther King Day," Fey told Entertainment Weekly.

"I want to lay claim to that bit before anyone gets it. It's a movie that has everyone in the world in it."

30 Rock, which kicks off its sixth season in the States this Thursday, will also feature such guest stars as James Marsden, Mary Steenburgen, Will Arnett, Denise Richards, Kelsey Grammer, and Kristen Schaal.
