According to The Hollywood Reporter, Steven Tyler's former manager has 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."

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."
