Taylor Swift and One Direction member Harry Styles were nominated for several awards at the 2013 Billboard Music Awards, to take place May 19, along with other well-known names in Hollywood.

Before they attend the award ceremony, a report surfaced that the Begin Again singer is angry at her ex-boyfriend for speaking about her in his One Direction movie, to be released in August. The couple split at the beginning of the year.

Although Swift had been writing about their relationship in her own songs, Britain's magazine The Telegraph reported that she is not happy with Styles talking about her in his movie This Is Us.

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

The singer is also upset that her ex-boyfriend had asked for all shots featuring Swift to be cut out from the film. She thinks this will present her negatively when the One Direction movie is released.

"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," said the source.
