On a quest to expand his emcee duties, the one-time A.C. Slater will host MTV's new series
Top Pop Group
The show will be similar to Lopez's other hosting gig,
America's Best Dance Crew
, only featuring music groups. Nine unsigned acts, who will be coached during the series, will take to the stage and do their best to impress the yet-unknown celebrity panel of judges. Viewers will vote for their favorite each week until there's one left standing. The winner receives $100,000.
Lopez, who also hosts

reporter Marianela Pereyra in case he spreads himself too thin.
A casting special, also hosted by Lopez, 34, airs Thursday on MTV at 9 pm/ET. The series premieres Sept. 11 at 10 pm/ET. -
