Actor Mario Van Peebles isn't stable -- well, his floor wasn't stable, according to a new lawsuit.
Adel Bebaway claims she bought Mario's condo on the beach in Playa del Rey back in 2007 for $1.375 mil, only to find later that the floor sloped like a mutha. Adel says the "Damages" star and his realtor lied about its condition during the sale.
In the suit, Adel also claims she found significant mold in the bathroom -- which Mario also neglected to mention.
As for Peebles' property company -- the best name ever ... "Mayamakaylomandela Properties" ... common spelling.
The suit, filed in L.A. County Superior Court, seeks unspecified damages.
Calls to Peebles' peoples have not been returned.
