She may have reportedly called off her engagement to Liam Hemsworth but it looks like Miley Cyrus is not letting relationship woes stop her having fun.

The Hannah Montana star has uploaded a clip of her shaking what her mama gave her in a sexy "twerking" video.

In the two-minute clip on the 20-year-old singer's Facebook page she dances to The Wop, J Dash's new hip-hop track.

She pops her booty and throws impressive shapes in her unicorn onesie.

One fan said: "I love her. She def did that. Good job Miley. All in good fun."

The sultry video comes amid reports that the former Hunger Games star and Cyrus have parted ways but she was refusing to call of their wedding.

The rumour mill went into overdrive in February after Cyrus was spotted without her engagement ring and friends claimed their relationship was on the rocks.

Recent reports suggested that Hemsworth, 23, had ended their two-year relationship because he had grown tired of her wild behaviour.

"Liam is fed up with Miley's brattish behaviour. She always needs to be the centre of attention," a source told the Sun.

"Her freakish transformation has also turned him off. He thought getting engaged would calm her down but she is always looking to make another change.

"He's done. He wants a quieter life."

The couple have not commented on the rumours.
