When you are the Queen of Christmas, naturally your children have to be elves.

Mariah Carey recruited two of the cutest co-stars for her latest Christmas music video: her twins Monroe and Moroccan.

The superstar promised her fans three Christmas presents on her website - Mariahsworld.com - and the first arrived in the form of a catchy dance version of Here Comes Santa Claus.

The diva rocked yet another jaw-dropping outfit; a figure-hugging shimmering red dress with a very generous helping of cleavage on display.

The five-bedroom, five-bathroom mansion features a stunning, open-plan lounge with a vaulted ceiling and a fireplace plus magnificent views over the mountains and town.

An elevator leads to the games room, which includes a pool table and a wet bar.

There is also a media lounge, a wine room and a gym for working off all those Christmas calories,

The house has ski-in, ski-out access to the Aspen Highlands Mountains so it's just as well it also has a sauna for easing aching muscles after a long day on the slopes.
