Miley Cyrus has slammed Taylor Swift for her Bad Blood music video. In an interview with Marie Claire, the 22-year-old former Disney star said that the video "promotes violence".

Cyrus is the host of 2015 MTV Video Music Awards and Bad Blood has been nominated for seven awards, including Video of the Year.

"I don't get the violence revenge thing," she said. "That's supposed to be a good example? And I'm a bad role model because I'm running around with my titties out? I'm not sure how titties are worse than guns."

The Red singer's feud with American singer/songwriter Katy Perry is well known, but with another singer joining the ranks, her credentials are being questioned.

Swift 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 had 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.

Recently, during Swift's concert in Foxborough, Massachusetts, when she was singing Bad Blood, and one of her backup dancers held up a shark puppet behind a glass panel.

Instantly, fans started speculating that the shark was a reference to "Left Shark", from Perry's Super Bowl halftime show performance earlier this year.
