Taylor Swift’s father Scott Swift allegedly penned a lengthy email about his family and the singer in 2005 – and it has since been leaked online amid a new lawsuit.

Daniel Dymtrow, who used to manage Britney Spears and also managed Taylor when she was just 13, is suing the Swifts.

He claims he was paid less than $10,000 for the work he did and the connections he gave to Taylor’s family.

He alleges that he was promised – both verbally and in writing – that he would be financially protected and supported by the Swifts.

Scott Swift let it rip in an email saying: “I am your banker and I am you and Taylor’s biggest fans.

“I will sell a s**t-load of t-shirts.” He went on venting: “Who gets to go to New York, New England and every cool appearance? Not dad.

“Can’t fix hair. Dad talks too much. Who pays for trips to New York? Dad.”

He didn’t stop there, blustering: “I am going to do anything that I think is appropriate to advance Taylor’s career,” before making a spiteful jab at his wife, Andrea, adding: “Finally, if you want to get rid of me, please forward this to Andrea.”

Fans have been buzzing with comments about the fiery email.
