Taylor Swift 'upset over Harry dig'

Taylor Swift is reportedly "raging" over Harry Styles making a dig at her in the upcoming One Direction documentary.

The 23-year-old American singer and the 19-year-old boyband member split up at the start of the year after an on/off relationship.

Despite Taylor famously penning tracks based on her own relationship problems, she is said to be furious that Harry calls her a "pain in the a**e" in the forthcoming One Direction: This Is Us.

"[She's] raging," a source told UK magazine Star."Taylor was really angry after she heard that Harry had spoken about her publicly, it's obviously very humiliating for her."

She is also said to be upset that Harry asked for all shots showing Taylor to be removed from the final edit of the documentary.

The pretty singer feels that this will show her in an even more negative light when the One Direction movie is released at the end of August.

"Fine, so it didn't work out between them, but she's been so careful not to mention his name when speaking to the press, and just wishes he would have the same courtesy," the source finished.

Taylor was recently irked by another ex-partner. In April it was reported that she felt "bitter" when she found out her ex-boyfriend musician John Mayer would be performing at the Academy of Country Music Awards.

"She said she had to go on earlier than him," a source told Us Weekly.
