Taylor Swift reportedly feels that Miley Cyrus envies her.
In an interview with Marie Claire, the 22-year-old former Disney star said Calvin Harris' girlfriend's Bad Blood music video "promotes violence".
"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."
Swift's song Bad Blood from her latest album 1989 has had over 427 million views on YouTube.
Adding on, for the 2015 MTV Video Music Awards, Bad Blood has been nominated for seven awards, including Video of the Year and Cyrus is the host for the event.
"Saying things like this is so typical of Miley. She is desperate for attention and will do anything to get it. It must kill Miley that Taylor has gotten so much attention for 'Bad Blood'. In Taylor's mind, Miley is just being jealous," a source said.
"She wants the spotlight on her and taking shots at Taylor is a good way to do it," the insider added.
Cyrus is also not in good terms with Swift's best friend, Selena Gomez.
Last year, the Wrecking Ball singer mocked the Come & Get It hitmaker during a concert in Milan.
Cyrus grabbed a cardboard cut-out of Gomez from a member of the audience while singing the song FU and then threw the cut-out back into the crowd.
Cyrus recited the lyrics to the hit song: "I got two, ooh, ooh letters for you, One of them's F and the other one's U, Cause what you gotta do, is go get yourself a clue, Only two, ooh ooh letters to choose, One of them's F and the other one's U, SMH, I'm pressing send on you'."
