Mariah Carey is carrying on with her life in Toronto.
The "Heartbreaker" songstress performed for the first time since she and James Packer called off their engagement, and really brought down the house. Mariah shut down an entire block in Canada Thursday night to sing at the annual Hudson's Bay and Saks Fifth Avenue Holiday Window unveiling, where she wore a red and pink Anna Maier gown.
Mariah didn't just perform "All I Want for Christmas Is You," she gave attendees a real show that featured fireworks and confetti. Fans dubbed her the "Christmas Queen" after her headline-making performance. The event was live-streamed on Facebook.
