Taylor Swift is being sued over a cancelled concert.

The 'We Are Never Ever Getting Back Together' hitmaker is facing a lawsuit after being paid in advance to headline a country music festival in Canada which has since been cancelled, reports TMZ.

Promoters for Capital Hoedown - which was due to take place in Ottawa in August 2012 - reportedly failed to put the concert together in time and it was subsequently nixed. Now the company which sold tickets for the event feels Taylor, 22, should use her sizeable fee to refund $1.8 million worth of ticket purchases, according to documents filed in New York federal court.

The singer's representatives contest, however, that her deal was not with the ticket company and thus she is not liable for the refunds. They also claim they have not yet seen the lawsuit.

Taylor has had previous brushes with the law; in 2010 she was reportedly sued by former manager Dan Dymtrow for breach of contract. He claimed he signed the 'I Knew You Were Trouble' singer aged 14 and helped her launch her career but her family conspired to fire him before he could earn a commission from her sales.

Dan's attorney Fernando Pinguelo said at the time: "They delayed and delayed [the deal] and got rid of my client and subsequently signed [another] deal and kept his commissions for themselves."
