Singer Mariah Carey was seen cuddling up to lookalike of her estranged-husband Nick Cannon, as she struggled to hold back tears in a performance here.

Carey, who sparked criticism from fans after an off-pitch performance earlier this month, recently put on an emotional performance at the Beacon Theatre here.

The star, who struggled to hold back tears during the performance of a series of Christmas hits, welcomed a backing dancer who looked strikingly similar to Cannon halfway through, before proceeding to dance and cuddle up to him mid-performance, reports mirror.co.uk.
