*Who knew comedian and actor Brandon T. Jackson had even more talent? Well, in the new comedy flick, “Big Mommas: Like Father, Like Son,” we now know he’s got some pretty decent rap skills, too.

Brandon’s skills as a spitter are on display in the new video for the film’s theme song “Imma do It Big.” T-Pain and One Chance who lend their vocal to the song make a brief appearance. Random scenes from the “Big Momma’s House 2″ sequel are flashed as well.

“Big Mommas: Like Father, Like Son” hits U.S. theaters on February 18. In the flick, Jackson plays FBI agent Trent Turner. He goes undercover with his stepfather, FBI agent Malcolm Turner (played by Martin Lawrence) at an all-girls performing arts school. Posing as Big Momma and Charmaine, they must find a murderer before he finds them.
