FAITH EVANS GETS SUED OVER PRIVATE HOME VIDEOS OF HER & THE NOTORIOUS B.I.G!

Biggie Smalls is smack in the middle of another heated battle in California -- but this time, the deceased rapper's wife, Faith Evans, is the one in the hot seat.

It's all over private home videos of Christopher Wallace -- videos that a company called Kaushi Entertainment wanted to use in a documentary.

In a lawsuit filed Tuesday in L.A. County Superior Court, Kaushi claims they struck a deal, approved by Faith Evans, in which they would fork over $30k for all of the movies.

Kaushi claims they paid up -- but Faith Evans, along with several associates, never handed over the goods.

Long story short -- Kaushi claims they got screwed and want more than $1,000,000 to make things right.

Calls to Faith's people have not been returned.
