Miley Cyrus and Selena Gomez feud has been going on long before the “Adore You” singer started twerking.

While the two former Disney stars shut down the feud rumors year back, the alleged fight between the two sparks once more following news that Miles had dated Selena Gomez’s famous ex-boyfriend Justin Bieber back in summer of 2013.

To worsen the situation Miley Cyrus allegedly dissed the “Come & Get It” singer in her Bangerz Tour Concert in Milan, Italy on June 8.

According to TMZ, Cyrus, 21, who infamously mocked the former “Wizards of Waverly Place” star in a YouTube parody in 2008, allegedly obtained a cutout of Selena Gomez from a member of her “Bangerz” tour audience and carried it onstage while singing her song “FU” – "I don't really have much to say/ I was over it the second that I saw her name/ I got two letters for you/ One of them's F and the other one's U." – before finally tossing it back into the crowd.

“It’s unclear what Miley’s beef with Selena is … but there was nothing subtle about her message,” according to the site’s report.

However, Miley Cyrus reportedly denied the allegations of her dissing Selena Gomez on her concert tour despite the pretty obvious footage.

Speculations are now circulating that the rekindled feud between the two Disney stars sparks over the alleged and short-lived “love affair” of Miley with Selena’s longtime beau back in 2013.

While the twerking queen vehemently denied the news, Life & Style (via ExtraTV) reported otherwise. “Justin and Miley were seeing each other behind her back last year,” according to an insider adding, that Miley allegedly spent a night with Bieber at his home following the former couple’s on again, off again breakups.

In addition to Life & Style’s original report (via HL), the magazine claims that Gomez together with her longtime friend Demi Lovato and Taylor Swift are staying away from the “Wrecking Ball” singer.

“Both Taylor and Demi know how heartbroken Selena’s been, and they hate what Miley did to her,” a source allegedly told the magazine. “All four girls used to be friendly, but when Selena heard Miley started making moves on Justin, it went downhill.”

Furthermore, an expletive-laced footage of Miley Cyrus surfaced the net on May, ranting about an unidentified ex during her concert in London, to which the said footage was immediately rumored to be directed toward her former fiancé, “Hunger Games” actor Liam Hemsworth.

Cyrus was quick to respond about the rumors and took to twitter her explanation saying:

 “Just FYI what I said the other night at G.A.Y. had nothing to do with Liam. I was just tryin to rile up the boys.”
