Mariah Carey is performing in a series of sold-out seasonal shows at the Beacon Theatre in New York City.

The 45-year-old songstress was in a celebratory mood as she stepped out for another fun evening on Tuesday.

Mariah was dressed to the nines in a teal-green, finely embossed and form-fitting trumpet gown with a flourish of a train and low-scooped neckline.

The dress showcased her curvaceous figure and was accessorised with a flowy grey scarf.

Mariah wore long sparkling earrings that peeked now and then from her curling hair, while her features were set off by a fine dusting of make-up.

Ever the star, Mariah smiled at fans while exiting her chauffeured vehicle, pulling her wrap closer around her shoulders.

Mariah was surprisingly cheery despite reports that her popular seasonal track All I Want For Christmas is now No. 2 – not N. 1 – on the list of most-played Christmas tunes this year, according to Us Weekly.

The mother-of-two – whose marriage to Nick Cannon ended about a year ago – made her romance with Australian businessman James Packer public after they were seen on holiday together in Capri.

Packer showed up in New York City to show his support before Mariah’s concert, and the singer posted a picture of the happy reunion on her Instagram page.
