STEVEN TYLER Slams 'Rude' Former Manager In Legal Dispute

Steven Tyler's former manager recently filed a lawsuit against the AEROSMITH singer's current lawyer, claiming she cost Tyler a $6 to $8 million pay raise in 2011 in his contract for another season with "American Idol".

Kovac Media Group (d/b/a Tenth Street Entertainment),which served as Tyler's personal manager, brought in a lawyer, Dina LaPolt, to help negotiate a new deal for the rocker at the end of "Idol"'s last season.

The lawsuit, which was filed in Los Angeles Superior Court, claims LaPolt told "American Idol"'s agent that Tenth Street Entertainment's principal, Allen Kovac, "overplayed his hand with his aggressive behavior" and that "American Idol" could get the Artist for cheap, thereby undermining and negating Kovac's/the Artist's position in the negotiations."

According to TMZ.com, Tyler filed a declaration on Monday (December 17) in which he explained why he fired Tenth Street Entertainment.

"My lawyer and trusted advisor since February 2010 on entertainment matters is Dina LaPolt, and her firm LaPolt Law, P.C. Since then, Dina has been my advocate and ally and terrific counsel to me," Tyler wrote.

"I know she has been sued by Allen Kovac's company regarding my management relationship with him, and that is an outrage and a travesty.

"I was under a personal management agreement with Allen Kovac's company, Tenth Street Entertainment, for almost two years — from January 2010 until August 2011. It is an understatement to say that I was very unhappy with the services and conduct of Allen Kovac. Among other things, he was disrespectful and rude to my business associates, insulted and verbally abused my fiancée, my lawyer, my family, my assistants, and my accountants. I wanted very much to end the relationship. In fact, I only signed with his company in the first place because Kovac employed Eric Sherman, a person I liked, and only because we agreed that Eric would be my manager — not Allen.

"Even though he agreed to stay out of things, Allen would not stop interfering in my matters and business, and I wanted to fire his company.

"After a contentious period, I finally was able to end my management contract with Allen Kovac's company and have any remaining commission obligations transferred entirely to Eric Sherman. This was my decision after discussions with my lawyer Dina, and I instructed her to proceed with a contract terminating my relationship with Kovac's company.

"By contract, all of my obligations to pay any management commissions to Kovac's company ended on August 1, 2011. On that day, Allen Kovac and his company completely released me and all of my representatives, lawyers, and agents, including Dina LaPolt and Eric Sherman, from any and all claims relating to my management agreement."

Tyler announced his departure from "Idol" in July after serving as a judge for two seasons on the hit Fox program. The AEROSMITH frontman explained that he wanted to refocus on his music career.

Although he seemed to enjoy his two-year stint on "American Idol", Tyler recently admitted that the show was actually "not my cup of tea." He said he only signed up for the show because he was feuding with his AEROSMITH bandmates and it was "something to do while the storm blew by."

He explained to Rolling Stone, "I loved it and hated it. It was a great job, I sat next to J. Lo and I made a ton of money. It was a moment in life and it became larger than life."

However — he said he didn't like the pressure he felt to be mean to the contestants. He explained, "The show's about kids and what you do to nurture their talent. They wanted me to take the piss out of the kids and I don't have that in me. That's not what I'm about. That's more about that other guy. Not me."
