Trina is fighting back against claims that she skipped out on a Missouri concert and cost a promoter thousands of dollars.
Lawyers of the promo-team claim she was paid $7,000 to perform at a club called Imperial Palace in St. Louis on May 19th.
Trina allegedly spoke up about a scheduling conflict, but never formally canceled -- so they were surprised when she wasn't there.
They now want to be compensated to the tune of $16,000. Trina's reps claim the hosts rejected her offer to refund the money before the show -- and were also wrong for telling people it was a performance when she was only supposed to be a hosting the event.
