Motley Crue shows are made even more entertaining by the antics of drummer Tommy Lee.  For many male fans, tops on the list is the portion of the show where Lee encourages ladies to show a certain part of their anatomy on camera. Right behind that is Lee's roller coaster drum solo. However, that drum design is now part of a lawsuit.

As previously reported, an engineer named Scott King wrote a letter to Motley Crue's lawyers, saying he pitched the idea for the drums more than 20 years ago and was turned down.  He claims Lee used his design during Motley Crue's 2011 tour, wants compensation, and threatened to sue.

Lee's lawyers responded to King's letter by denying Lee stole King's idea. Now, according to TMZ, King has officially filed suit in Los Angeles Superior Court. He is demanding at least $400,000 in damages.

Meanwhile, Lee is about to turn 50, and apparently he made a pact with ex-wife Pamela Anderson that if they were both single at 50 they would remarry. But Anderson recently told Ellen DeGeneres that she doesn't remember making that pact.  So it doesn't look like a reconciliation is in the cards.

Anderson has been in the spotlight lately, being the first person to be eliminated in the current all-star season of  'Dancing With The Stars.' The couple divorced in 1998, but have two kids together and remain close.
