I loved this movie and own it too. It's a guy who goes under cover for case and has to dress up like a women. One the most funniest movies out there. Worth the watch.

What do you think, have you seen it?

After stepson Trent (Brandon T. Jackson) witnesses a murder, FBI agent Malcolm Turner (Martin Lawrence) brings back Big Momma, his plus-size alter ego, to help solve the crime. Big Momma goes deep under cover at a girls school of the performing arts, but this time he has Trent and Trent's female alter ego Charmaine as backup. The duo must try to find the killer before the killer finds them, but complicating matters is Trent's crush on a student (Jessica Lucas).

Martin Lawrence is positively hilarious as Big Momma. He fits in quite nicely at the girls school and really helps these girls. A zany adventure full of funny moments.
