Mariah Carey bundled up and braved the cold temperatures as she helped close the ski season atop the Tyrolean Alps in Ischgl, Austria, on Monday. The pop diva, whose twins Monroe and Moroccan turn one today, performed some of her hits in the wintery wonderland just days after celebrating her fourth wedding anniversary to Nick Cannon in Paris.

“I’ve never seen anything like it,” said Mariah, who was in awe of the majestic mountains.
