Miley Cyrus and Taylor Swift are about as different as two pop stars can be, so perhaps it should come as no surprise that the ladies don't always see eye-to-eye.
A source tells celebrity gossip magazine OK! that Miley has started openly insulting the singer in hopes that her comments will "circulate back to Taylor."
Taylor was reportedly "disgusted" by Miley's VMA performance (she certainly wasn't alone on that one), and now Miley is firing back at Swift.
"She thinks Taylor is stuck up and can't stand how prissy she is," says the insider. "She's telling everyone that Taylor is a sexless frigid ice princess who bored Harry Styles out of bed."
So why the alleged smack-talking campaign? Well, the source says Miley is really that pissed about Taylor's VMA comments from last year:
"That's the one thing Miley can't stand - women being b!tchy to other women."
A problem she apparently deals with by being totally b!tchy to other women.
If any part of this rumor is true (big "if"), we're guessing Taylor is none too worried about the shots being fired by Miley.
For one thing, a recent survey declared Taylor the Biggest Celebrity Player, so being called out as "sexless" probably wouldn't be too bad for her reputation.
Also, if Swifty likes making fun of Miley's performances, she's got plenty to work with. Miley's Beatles cover at the Billboard Awards, for example.
Sure, she kept her tongue in her mouth, but it still made our ears bleed:
