Taylor SwiftSince 2007, Taylor Swift's former manager has quietly waged a war with the singer's parents, who he claims cheated him out of millions by firing him just before she achieved major commercial success, THR, Esq reports.

Dan Dymtrow signed Swift in 2004, when she was 14, and claims in court papers to have steered the singer on the path to stardom before Scott and Andrea Swift allegedly conspired to shut him out to avoid paying the 5-10 percent commission he was promised.

Dymtrow claims that he introduced Swift to Scott Borchetta, CEO of Big Machine Records, who eventually signed the singer.
