Miley Cyrus strikes down Selena Gomez; fight over Justin Bieber?

After all her bizarre antics Miley Cyrus has yet again managed to raise eyebrows onstage, but this time she involved another major celebrity. Or at least her image.

While belting out her angry 'FU' song the Wrecking Ball hit maker snapped up a crude cardboard cutout of Selena Gomez's face, looked at it, and very aggressively threw it into her screaming audience.

The cutout was vulgar at best with a color photo of Selena's head taped onto a carboard cutout of a body where a bikini top and certain parts were drawn in by black pen.

Friends close to the duo claim they have had issues since they both dated the former Jonas Brothers star.

Miley Cyrus' friendship with Selena Gomez reportedly "turned sour" in 2008 when the 'Spring Breakers' actress began dating the 'Wrecking Ball' hitmaker's ex-boyfriend Nick Jonas.

A source close to Selena, 21, told E! News that she has always taken the "high road" with Miley, but has never really liked her.

The insider added: "This has been going on for a while."

Meanwhile, a friend close to Miley said: "Their issue dates back to their Disney days... Things turned sour after Miley broke up with Nick Jonas in late 2007. The following year, Nick began seeing Selena and that is when the beef blew up."

While it appears there's no love lost between Miley, 21, and Selena, the blonde singer is good friends with her rival's on-again, off-again boyfriend Justin Bieber.

The hatred for the WIzards Of Waverly Place actress could be over Justin Bieber as well, TMZ reported.

The site claimed Cyrus and Bieber 'hung out' last summer after she presented him with a Billboard award in May. The Nashville native denied any romance.

Miley and Justin have been friends for many years but grew closer in 2013 as the Last Song star was breaking up with fiancé Liam Hemsworth.

In February Star magazine reported Gomez had a hard time in her Arizona rehab and confessed it was over a friend's betrayal.

'She told the group how much she was struggling with Justin’s infidelity and his obsession with hooking up with other women,' an insider said.

'She learned from mutual friends time and again that Justin was cheating, and that knowledge was breaking her heart.'

Miley and Selena have known each other since they were both young actresses on their Disney TV shows that made them famous. While Gomez was lighting up Wizards, Miley was the heart of Hannah Montana.
