Indeed the above photo was taken inside; Mariah was merely trying to gear herself up for a nocturnal dog walk, in the snow, wearing nothing but a red bikini. Do scroll down.

No, she doesn't look nearly as comfortable in the below shot... Has to be said, though, lady knows how to get herself noticed - and some column inches in the process.

In her defense, apparently bringing your dog for a walk in the snow while bikini clad is a Christmas tradition in Aspen. Hey, we've been known to hurl ourselves off the Forty Foot into the icy Irish Sea of a Christmas morning, so we can't exactly judge. Then again, we probably wouldn't be so quick to post any photos of said festive mania on Instagram...
