Mariah Carey just snagged a W against a concert promoter who claimed the diva cost them millions of dollars in damages for allegedly bailing on scheduled concerts in South America.

The lawsuit stemmed from legal action MiMi originally took against FEG Entretenimientos S.A. when she claimed she did not receive proper payment for the scheduled appearances, which then forced her to cancel.

The promoters countersued and accused Mariah of defaming them in a tweet that read, "Devastated my shows in Chile, Argentina & Brazil had to be canceled. My fans deserve better than some of these promoters treated them."

FEG wanted $3 million -- $2 million for the defamation claim and another $1 million for bailing on the concerts.

On Wednesday, the judge in the case dismissed the defamation claim against the singer, and noted that her tweet was an "opinion." He explained that the words "deserve better" are vague and did not damage the promoters.

Mariah is personally clear of the $2 million claim, however her entertainment company is still possibly on the hook for the remaining $1 million for the botched performances.

Her case against the promoter is also ongoing.
