Singer Taylor Swift may be left without any backup during the MTV Video Music Awards (VMA) on Aug. 30 hosted by Miley Cyrus, with whom Swift is currently feuding, and she’s not very happy about it. Swift’s boyfriend Calvin Harris will be performing in the U.K. at the time and will not be by her side to protect her from Cyrus.

The “Wrecking Ball” singer had criticized Swift’s “Bad Blood” song in an interview for Marie Claire’s September issue, triggering a feud. Cyrus had said in the interview: “I don't get the violence revenge thing," adding: "That's supposed to be a good example? And I'm a bad role model because I'm running around with my [breasts] out? I'm not sure how [breasts] are worse than guns."

Swift's boyfriend also got involved in a Twitter war with Zayn Malik, 22, after the former One Direction singer retweeted a message in favor of Cyrus, leading to a feud between the two male singers as well.

“Taylor is thrilled Calvin is the kind of guy that jumps to her defense. She was happy when he tweeted Zayn,” a source told Hollywood Life, adding: “But she knows it probably just gave Miley more reason to bash her. She wishes Calvin would be there with her to be her human shield.”

Another source earlier told Hollywood Life that Swift was planning to surround herself with her "girl squad" at the VMA to avoid Cyrus. “Taylor is by far her biggest target and Miley is thinking of ways to subtly diss her. She loves the controversy and is upset that Taylor hasn’t said anything about it. There is bound to be sparks between the two of them that night,” the source said.

A third source reportedly said: “Taylor would love to have all of her girls that did the ‘Bad Blood’ video with her. Karlie (Kloss), Cara (Delevingne), Gigi (Hadid), Selena (Gomez), all of them.

"And if she wins, she wants them to come up on stage with her. Taylor has more than enough awards to last a lifetime. She just wants to share the success with as many people as she can.”
