The Kardashians didn't have an easy time on the red carpet at Sunday's Emmy Awards!

Pregnant Kourtney, 30, admitted she struggled picking out a dress to cover her bump -- and now her sister Kim says she had a wardrobe malfunction.

"I had this beautiful white gown by Ina Soltani and in the car on the way over, my entire zipper ripped!" the reality star, 28, blogged Monday. "It just popped! I freaked out and called my stylist, Monica, who was at the Emmys waiting for me with a needle and thread to sew up my entire dress!"

The process took about 30 minutes, forcing her to miss some joint interviews with her seven-months-pregnant sister.

"I couldn't believe it," Kim said.

Still, she added: "I made it in time to go to the show and the Emmys was such an amazing experience! Everyone was so glamorous! Drew Barrymore, Tina Fey, everyone was there! What a great show!"
