Preceded earlier this month by a half-hour preview special, this hit reality competition series officially launches Season 6 tonight and Tuesday, with host Nick Cannon welcoming returning panelists Nicole Scherzinger, Ken Jeong, Jenny McCarthy and Robin Thicke. Confirmed as guest panelists are will.i.am, Joel McHale, Leslie Jordan and Cheryl Hines. There's a significant change in the show's basic format, though, with just two featured groups of contestants, Group A and Group B. The winner of Group A will face off against the Group B winner in the season finale.
