The Keeping Up With The Kardashians star was snapped exiting Barneys New York in Los Angeles on Monday afternoon (6 January) and handing a wad of cash to the valet when she picked up her car.

Kim was dressed in her usual uniform of skin tight clothing and an oversized coat, teamed with heels.
She gave us a glimpse of her stomach – and cleavage! - in a cream crop top, teamed with a high-waisted, stretchy turquoise skirt.
Perhaps the mother-of-one was keen to show off the results of her gym routine? After all, she did take to Instagram over the weekend to post shots of her post-pregnancy bum and tum…

"I hadn't skied in 10 years and it's not too fun having all the paps stand there waiting for a fall! LOL," she wrote. "But now we have these cute pics and good memories! Kourtney had gone the year before and assured me I would remember how. We always skied with our dad and I hadn't gone since I skied with him. It was so good to be out skiing again!"
