The trio discussed their work, personal lives, Kourtney's decision not marry Scott Disick and their nail polish line, which was worn by Kimmel. Kim even told Kimmel that she “should thank" him for his part in her getting to know her new boyfriend, Kanye West, better.

Kourtney, whose baby bump was the focus of the interview, discussed why she is not trying to marry the father of her two children. Apparently, she has commitment issues.

 "I'm really claustrophobic and all my issues -- and I have a lot of them -- they all stem from this thing," she explained. "I can't commit to anything. I love Scott and he is my partner."

All the K Girls were wearing sexy black dresses, but no one noticed Kim's awkward wardrobe malfunction during the interview. No one, that is, except Kim's Instagram fans.

Kim had uploaded an Instagram picture of the back of her skin tight black leather dress for her salivating followers. It showed a very large split at the zipper.

She tweeted just before heading onstage, "About to do Jimmy Kimmel & my whole dress rips! Help!!! Time to sew me in...praying this works."

Amazingly, it did.

This is not her first attempt to up her growing number of Instagram followers. She recently posted a sexy photo of herself on all fours, wearing a black thong, black high boots and a black leather jacket.

She wrote: "Thanks to all you 2 million sexy beasts out there for following me on Instagram! So heres a little present."
