Miley Cyrus and Liam Hemsworth have called off their engagement.

It was reported the Wrecking Ball singer and the Australian actor were on a break, and representatives for the former couple have confirmed they are no longer engaged.

According to People magazine, they have been told by representatives that Cyrus and Hemsworth's relationship is officially over.

It was previously said the couple - who have had a "tumultuous relationship" - were "exhausted" and things weren't looking good for their romance.

A source had said: "They've split for now. Miley and Liam have a very tumultuous relationship and both are exhausted.

"It's a complicated relationship. The wedding is on hold, for now. It's not cancelled but it doesn't look promising."

The We Can't Stop hitmaker had been criticised after her risque performance at the MTV Video Music Awards last month, and Hemsworth was said to be "mortified" after the display.

An insider claimed: "Liam really does care about Miley, but her racy new look and sort of ghetto attitude isn't exactly what he signed up for.

"Her VMAs performance absolutely mortified him and he couldn't be more embarrassed. He doesn't really see anything sexy about what she did on stage."
