Iggy Azalea has tumbled off the stage during an MTV Video Music Awards benefit concert.

It is not known if the Australian rapper was injured.

She fell off the stage while performing her hit Fancy at The Avalon in Los Angeles last night.

Security guards quickly pulled her back on to the stage, and she barely missed a beat as Charli XCX joined her for the chart-topping single.

Afterwards she told the crowd she felt "very blessed" that she did not break her legs.

She appeared unharmed and in good spirits, even posting a video of the fall on Instagram. She wrote in the caption: "I know I laughed."

Tori Kelly and Sam Smith also performed at the event benefiting Lifebeat - Music Fights HIV/Aids.

Iggy is up for seven awards at the VMAs.
