Miley Cyrus and Liam Hemsworth are regulars on celebrity news sites. Now, the Hot Instagram lover, 20, has allegedly cheated and kissed another man.

The couple's troubles are reaching an all time high after the "Wrecking Ball" singer's recent Video Music Awards performance, according to Hollywood Life.

But their relationship has been rocky for a while now. And Cyrus could be the central cause of the tension after she supposedly made out with one of her guy friends, said a new inTouch report.

While out partying with MTV's Rob Dyrdek in New York City on Aug. 23, the controversial singer reportedly locked lips with a guy pal. The group was out celebrating at 10ak when the kissing started that night.

"She was pretty out of control," a witness said about Cyrus.

Cyrus apparently got very flirty with her friend, with her fiance missing in action. And now, Cyrus and Hemsworth are reportedly not speaking to each other after having a big fight right before the singer hit the VMA stage.

The "We Can't Stop" songbird allegedly used her raunchy MTV performance to blow off steam after her fight with Hemsworth. But, her fiance jetsetted to London to seek advice from his older brother, Chris Hemsworth after their fight.

The "Paranoia" star explored London's nightclub scene with the "Rush" actor, reported HL.
