TBS has announced the lineups for two stand-up comedy specials it'll tape and broadcast from the inaugural Just For Laughs Chicago festival in June. So who's added to the bills?

Martin Short will host Let Freedom Hum (tapes June 18 at The Vic, and airs June 26), with performances by John Pinette, Kathleen Madigan, Greg Giraldo, Tom Papa and Jeremy Hotz.

The following night, David Alan Grier will host Comedy You Can Believe In (tapes June 19 at The Vic, and airs June 28), with performances by Bruce Bruce, Jo Koy, Mark Curry, Aries Spears and Marina Franklin.

TBS previously announced its intentions to produce and broadcast a third variety special for Ellen DeGeneres at the Chicago fest, and that will air June 27. Tickets for the Martin Short special will go on sale this Friday. Tickets also are available for a fourth show with George Lopez during the fest, as the previously three Lopez shows already have sold out.
