Jamie Foxx, here to play a district attorney in the movie "Law Abiding Citizen," had a busy Saturday night.

He dined at Ms. Tootsie's on South Street, attended the Ludicris concert, and visited G Lounge at 17th and Chestnut.

Foxx stars with Gerard Butler in the psychological thriller (see info here). As they're in rehearsal before shooting starts Jan. 21, the two have been seen all around Rittenhouse Square.
