Singer/actress Miley Cyrus has taken aim at fellow Disney stars Selena Gomez and Demi Lovato in a new online video.

The Hannah Montana star, 15, has posted new footage of herself and her best pal joking around as they mock an earlier video made by friends Gomez and Lovato, in which they talk about their love of make-up and cartoon characters Teenage Mutant Ninja Turtles.

In her own take on the chat, Cyrus boasts about a new Teenage Mutant Ninja Turtles T-shirt she's bought, saying: "I got a really cool shirt today. Like, really emo, like emo-mazing."

Cyrus' video has now been interspersed with Gomez and Lovato's footage and posted on video-sharing website YouTube.com to show a frame-by-frame comparison of the two.

The attack has sent online gossips into a spin, with many speculating that Cyrus' actions were prompted by reports her ex-boyfriend Nick Jonas is dating Gomez.

However, both Jonas and Gomez, who appears in The Jonas Brothers' new Burnin' Up video, have denied the claims.
