Brandon T. Jackson boards 'Big Momma's House 3'

The big momma will soon return to the big screen, as Regency is moving forward with "Big Momma's House 3," a sequel that will see Martin Lawrence reprise his role as undercover agent dressing up as an obese chick. I know... it really is the worst idea ever.

Anyway, Variety reports Brandon T. Jackson, who's on the screen in "Percy Jackson and the Olympians: The Lightning Thief," is joining the project directed by John Whitesell ("Big Momma's House 2"). Matthew Fogel wrote the script, which Randi Mayem Singer revised.

The story? This time, Lawrence's character Malcolm takes his 17-year-old nephew on an undercover mission at an all-girls performing arts school after the youngster witnesses a murder. They both dress up as ladies, trying to find the killer in time before he strikes next.

This one blows already. Word is also the tilm may not be titled "Big Momma's House 3." We'll see what happens. Raja Gosnell's first "Big Momma's House" grossed $117 million domestically, while the first sequel "Big Momma's House 2" bagged $70 million.
