Victoria Azarenka's grunt to become music

The signature grunt of world number one Victoria Azarenka has been used in a new track by LMFAO frontman Redfoo.

Particularly when she is serving, the noise that is made by the Australian Open champion has been compared to a number of sounds - including that of a Jumbo jet taking off.

Redfoo, who is a friend of the Belarusian player, has mixed her grunt into a new single due for release in the coming weeks.

"It's my grunt. It's not my vocals," Azarenka clarified to reporters. "I don't take high-key or low-key there. It's just natural."

Azarenka is currently in Melbourne, where she has reached the quarter-finals of the Aussie Open.
