Two can play this game!

Brandi Glanville has already sought legal counsel in preparation of the premiere of ex-husband Eddie Cibrian and new wife LeAnn Rimes' reality show, Life & Style reports.

The former model and the TV actor had a clause in their divorce agreement that banned them from publicly bad mouthing each other, and while at the time that was more of a concern for the Playboy Club star, it's now also a concern for the Real Housewives of Beverly Hills star.

"Eddie was worried that if Brandi bad-mouthed him, it would hurt his career. But the clause works both ways and she thinks he and LeAnn have completely violated it," a source dished to the mag.

The Bravo star is not getting litigious out of spite, either! "She doesn't give a crap what they think about her behind closed doors. But to attack her on TV, where it can affect her children - it's disgusting," the source added.

Can't LeAnn and Eddie just go back in the swamp they crawled out of?!
