Taylor Swift's former manager is suing her for millions of dollars in commissions.

According to The Hollywood Reporter, Dan Dymtrow says he discovered Swift, signed her in April 2004, and helped build her career. He was axed a year later, right before Swift signed a deal with Big Machine Records and became a superstar.

Dymtrow claims that his deal with Swift and her parents allowed him to be paid between 5 and 10 percent commission from Taylor's music career, and that he was fired so the Swifts could avoid compensating him. "They delayed and delayed [the deal] and got rid of my client and subsequently signed the deal and kept his commissions for themselves," Fernando Pinguelo, Dymtrow's attorney, told the Reporter. Dymtrow also said he introduced Swift to the agents that ended up in charge of booking her concert gigs so he's entitle to profit from forming that relationship.

Swift's lawyer Paul LiCalski told TVGuide.com, "We don't comment on pending litigation."

A letter submitted to the New York Federal court by both parties on Wednesday stated, "Mr. Dymtrow seeks to prove that key deal points that were being discussed during his tenure were, in sum and substance, consistent with the points that were further negotiated and signed after his term as a manager."

No trial date has been set.

An email to Dymtrow's attorney was not immediately returned.
