Pop singer Mariah Carey was handed legal victories Wednesday in a back-and-forth breach of contract litigation spurred by the cancellation of two concerts in South America in 2016.

U.S. District Judge William Pauley III of the Southern District of New York dismissed, in part, a set of claims against Carey and her front company, Mirage Entertainment Inc., including defamation claims against the famed singer over a tweet that appeared to lay the blame for the cancellations at the feet of promoters.
