Chris Meloni -- of "Law & Order: SVU" and "True Blood" fame -- was in town this weekend, according to his Twitter account (@Chris_Meloni). 

Meloni's visit may have flown under the radar, but he took time out to trade tweets with fellow TV actor and noted Ravens fan Josh Charles (@MrJoshCharles). 

Charles -- a Baltimore native who stars in the CBS drama "The Good Wife" wrote Meloni: "Why are you in Baltimore? The people want to know." 

Meloni coyly replied: "Top secret assignment ..."

A little later Meloni teases Charles with the line: "Tired of getting kicked outta the Balto bars, have stopped using ur name. Thx anyway."
