The third instalment in the Big Momma's House comedy franchise stars Martin Lawrence as an FBI agent who disguises himself as a woman to solve crimes.
The new Yogi Bear film dropped one place to number six, while Disney's Tangled fell four places to seven.
Both these and Adam Sandler comedy Just Go With It fared better than Justin Bieber's documentary Never Say Never, which entered the chart at nine with takings of just over £800,000.
On a screen by screen basis, the 3D concert film was also beaten by Inside Job, a documentary about the recent economic meltdown.
