Taylor Swift is involved in a hefty $2.5 million lawsuit for keeping the paycheck for a canceled performance at a large country music concert in Canada.

Swift allegedly kept the upfront fee that she received to headline Capital Hoedown music festival in Ottawa Canada, last August, even after the event was canceled.

The event was allegedly canceled because of producers unable to organize the concert on time and brought the lawsuit against Swift to return the money she was paid in order to cover the ticket company's loss in ticket refunds.

Florida-based ticketing company FIRE USA Inc. filed a lawsuit in New York federal court against the singer claiming, "Swift and/or through her agent Messina refused to perform and/or reschedule a new appearance," which "amounted to breach" of contract.

Grammy winner singer is sued after customers demanded their money back of the purchased tickets through Evo Merchant Services, a New York credit card payment processing company. Then the payment company filed a claim against FIRE.

Evo seeking to cover the $1.8 million losses claiming FIRE refused to turn over the money in violation for their contract, forcing the ticket company to take legal action against Swift.

The singer has been involved in legal battles before when her former manager, Dan Dymtrow filed a lawsuit against Swift in 2010 claiming that her family owes him large amount of money for discovering her, according to The Hollywood Reporter.

Country star rep reportedly told TMZ that Swift never made a deal with the ticket company and hasn't seen the suit yet.
