The pending appearance comes on the heels of her recent stint on "American Idol," when she acted as a mentor to the four finalists.

Details of the upcoming "Dance" gig were not immediately available, The Hollywood Reporter said.

The Reporter said the appearance, which was first reported by the Hollywood Web site Popeater, would have Gaga joining the judging panel later this season.
