Pop rocker Avril Lavigne is suing concert organisers over allegations she has yet to be paid for a gig she performed in New York City last year (13).

The Sk8er Boi star alleges bosses at live streaming company 2VLive agreed to pay her $500,000 (£294,118) in three installments to perform the gig on 25 September (13) and carry out a number of promotional appearances.

In legal documents, filed at a court in Los Angeles and obtained by Tmz.com, Lavigne claims she received the first payment of $125,000 (£75,529), but has yet to be handed the rest of the money.

She is suing to recoup the cash.
