Oh look, it's the least interesting K sister!

Kourtney Kardashian hit the studio to do some voiceover work for Keeping Up with the Kardashians yesterday, and the reality star wore a boring denim-on-denim ensemble that does little for her figure. Kimmy K should give her sibling some style tips, because she doesn't seem to have any fashion sense.

The mother-of-three might want to put a little more effort into her appearance, because it sounds like boyfriend Scott Disick isn't even into doing the dirty with her anymore. "It's kind of just like a boat that capsizes. You know, you just tip it over and hope she doesn't fall off the bed. It's bad. It's real bad," he said about his then pregnant girlfriend on a recent episode of KUWTK.

We would be nicer if she wasn't so terrible!
