Limp Bizkit frontman Fred Durst joined Avril Lavigne at her show last Thursday during a performance of her hit 'Complicated'.

Durst came onstage in Lowell, Massachusetts wearing an 'I (heart) Avril' shirt and Lavigne climbed on his back during the duet.

Two members of the audience also took part in the song.

Lavigne is due to release a live record on 9 September and MTV reports that the duet with Durst could make the tracklisting.
