Lawsuit.

Motley Crue is now part of a Steven Tyler lawsuit.

The lawsuit between Steven Tyler's former manager and his lawyer has taken a new twist -- two members of Motley Crue are now involved.

The onetime management company, Kovac Media Group, filed suit against the lawyer, Dina LaPolt, claiming she botched Tyler's American Idol contract negotiations, which prompted him to quit the show. Allen Kovac now claims that LaPolt has been “conspiring” to “set up a competing management company” to steal away a “world-famous rock band” that he's managed for 15 years. That group is Motley Crue, and two of its members, Tommy Lee and Mick Mars, have filed declarations objecting to Kovac's claims.

Mars says he was "completely shocked and mad that Motley Crue's manager had sued our lawyer. I trust Dina implicitly, to the point that she is my trustee if I die or become disabled... Any strain between Motley Crue and Allen Kovac is caused by Allen Kovac's actions."

Lee says, "Obviously, I would have the right to know that they were having problems performing under our management agreement."
