Kourtney Kardashian Baby Bump 2014: 'KUWTK' Star Debuts Pregnancy Bikini Body

Kourtney Kardashian has debuted her baby bump.

During a day at the pool on Sunday, the 35-year-old Keeping Up With The Kardashians star put her growing belly on display for a photo she later posted to her Instagram account.

“Sundayzzzz,” Kardashian wrote in the caption of the photo, according to a June 23 report by In Touch Weekly. In the photo, Kardashian was seen jumping into a pool with several of her girl friends while wearing a skimpy gold bikini.

Earlier this month, on an episode of Keeping Up With The Kardashians, Kardashian confirmed the news of her third pregnancy, telling longtime partner, Scott Disick, “I’m pregnant.” Although the pregnancy appeared to be unplanned, a source later revealed to Us Weekly, via Yahoo!, that Kardashian and Disick were trying for a third child -- and that Kardashian was hoping for "a handful of kids." The source also noted that Kardashian was a few months along.

In 2012, Kardashian hinted that she and Disick's family would continue to expand, revealing she was contemplating another child and no longer taking birth control on an episode of Keeping Up With The Kardashians.

"I need to see what it's like when I have two, but [having kids] is what life is about," she said at the time. "I'm not going on the pill. I don't believe in it anymore!"

Kardashian’s third child, who is reportedly due this December, will join her and Disick’s two older children, son Mason, 4, and daughter Penelope, 1.

Keeping Up With The Kardashians airs on Sunday nights at 9 p.m. on E!
