Most women give up on trying to look sexy during pregnancy, but not Kimmy K!

Kim Kardashian and her sister Kourtney hit up the studio today to shoot some stuff for Keeping Up with the Kardashians, and the pregnant reality star flaunted some major cleavage in a see-thru dress with a black lace bra. Kourt, meanwhile, appears to have stolen Khloe's style and was sporting a navy bodysuit with tight jeans.

The brunette bombshell and husband Kanye West are getting ready to welcome their son in December, and she recently admitted that she's "a little" worried about daughter Nori's adjustment to having a sibling. "We read books with her about getting a baby brother and a new sibling all the time! We always say goodnight to baby brother," she wrote on her website.

The world's most famous woman might have a lot on her plate these days, but she makes quality time with her man a priority.

"It’s still SO important to me to make time for my husband. Our schedules are already so busy and I know that the first few months when the baby comes will be harder and more hectic. I know how important it is to do things on our own. We’ll definitely go on a movie night and go out to dinner. It’s important in any relationship to make quality time together a priority! [He] really is the best partner. I wouldn’t want to go through any of this without him by my side!” she added.

We hate to admit it but Kim still looks damn good!
