My Mom's New Boyfriend (2008)

Henry is a young FBI agent. During a three-year absence from his home in Shreveport, his mother Marty loses more than 100 pounds, looks great, and to Henry's embarrassment, has become a party animal. Within a day of Henry's returning home with his fiancée, Emily, who's an FBI profiler, Marty meets Tommy, a suave foreigner. He's posing as a consultant, but he's an international art thief, in town to steal "Mother and Son," a Bernini sculpture. Henry is detailed to head a team keeping his mom's new boyfriend under surveillance. Love, law enforcement, and filial devotion are set to collide.
