Kim Kardashian sunglasses cleavage boobs big butt gym work out

It may be early and a bit nippy out, but that's not stopping Kim Kardashian from getting her booty out of bed and hitting the gym!

Shortly after 8am, Kim was snapped arriving at Barry's Bootcamp in Studio City, and a little bit later we caught the freshly-showered reality starlet leaving her house to work it for the cameras ... presumably while reality TV cameras are rolling. Kim tweeted, "At a cover shoot today! Can't say which one but I've never shot for them before and I'm excited! Can't wait for you guys to see!"
