Taylor Swift and Katy Perry feud: Red singer will 'never talk about' Roar hitmaker in interviews

American singer-songwriter Taylor Swift has revealed that she won't talk about her alleged feud with Katy Perry in public.

The 25-year-old Red singer and Perry, who have previously dated John Mayer, were best friends for a long time before things got bad between the two.

In an interview with Rolling Stone magazine, Swift revealed that the song Bad Blood from her latest album 1989, is about a former friend. The two apparently fought over backup dancers.

Perry took a dig at Swift during the 2015 Super Bowl half-time show, which took place on 1 February at the University of Phoenix Stadium in Arizona.

During the performance, the 30-year-old singer's backup dancers wore high-waist polka dot bikinis, something similar to what Swift had worn while holidaying with Conor Kennedy on the shores of Hyannis Port, Massachusetts in 2012.

During an interview with the Telegraph, Swift said she will not say anything against the Roar singer.

"I'm not giving them anything to write about. I'm not walking up the street with boys, I'm not stumbling out of clubs drunk. But I'm never going to talk about her in my interview. It's not going to happen," she said.

Adding on, the Grammy Award-winning singer, who has a history of dating high-profile celebrities including Jake Gyllenhaal, Joe Jonas, Taylor Lautner and Zac Efron also talked about her dating life being in the media.

It was previously revealed that Swift has been single since splitting up with One Direction star Harry Styles.

"There was a bit of a reputation for having a lot of boy-bashing songs. Which is a sexist way of saying heartbreak songs. To trivialize someone who's heartbroken is really cruel. But people have to simplify things. Everybody's got busy lives, they don't have time to form a complex opinion of me and my music. I'm in a different place in my life, where love isn't really a priority. I haven't dated anyone in years so there's less chatter about the serial dater thing. I'm just really excited at an awards show when they don't make some weird joke about my dating life," she said.
