The Aerosmith lead singer’s former manager says lawyer Dina LaPolt poisoned Steven Tyler’s contract renegotiations with American Idol, costing him a multimillion-dollar raise. Kovac Media Group/Tenth Street Entertainment today filed an $8 million lawsuit (read it here) against the entertainment lawyer and her West Hollywood firm. American Idol and its former judge are not named as defendants in the breach of fiduciary duty complaint. In fact Tyler is not named at all. Instead he is referred to as “The Artist” throughout the filing, though it is pretty clear from the players, his membership in a band and his role as judge for two seasons on the Fox show exactly who he is. The suit claims that in 2011 LaPolt lost “hot commodity” Tyler a $6 million to $8 million raise in his Idol contract for a second season on the show.
