The 46-year-old singer put on quite the display at the viewing party for reality series Mariah's World in New York City on Sunday night.
She was not alone at the event as she was got up close and personal with new boyfriend Bryan Tanaka.
Her signature blonde locks were worn down flowing over her shoulders as she accentuated her looks with natural, complimentary make-up topped off with a swipe of pink lip.
Toyboy Bryan, 33, went for a James Dean inspired look with a black leather biker jacket over a white shirt and black skinny moto jeans.
The first episode of Mariah's new reality show gave an eye-opening look at her personal life as it showed her relationship with former fiancé James Packer before it broke down.
The docu-series also featured her new love Bryan who took center stage as the eight-part Mariah's World premiered on the E! network and its sister channel Bravo.
While Australian billionaire James, 49, appeared on screen for little more than 10 seconds, the 33-year-old dancer was repeatedly seen exchanging smiles, jokes and lingering looks with Mariah, 46, as they rehearsed for her European tour.
Despite Mariah's then-fiancé James barely appearing on screen, the singer spoke of him fondly as she showed off the yacht he had arranged for her to stay on off the coast of Capri.
'It's so beautiful here,' she said. 'This was a surprise from James to have. Look there's his yacht over there.
'My fans say James has so many responsibilities and I'm a night person. I work better at night, I'm more creative at night. It's not easy for us to spend every day together but when we do things we have great moments together.
