Pregnant Kourtney Kardashian Looks Sweet And Summery In White Playsuit

Celebrity bump watch is becoming a serious sport this summer, with so many of our favourite stars expecting - from Rachel Bilson to Mila Kunis, but after revealing she's pregnant last week, Kourtney Kardashian isn't showing, just yet.

The mum-of-two headed out for ice cream with her 4-year-old son, Mason in Southampton, New York. The pair walked hand-in-hand as they tucked into their snacks.

Kourt was looking suitably summery in a white playsuit, which she matched with seriously high brown leather and wooden wedges. She finished the look with her long brunette locks worn loose in soft waves. A summer style we're definitely keen on copying.

Despite the tight waistband on her tailored outfit, she didn't appear to be bearing a bump so far.

Also - check out the 'Yeezus' T-shirt Mason has on - Kourt's got him showing support for his new uncle Kanye, it seems.

Kourtney was seen breaking the news of her third pregnancy on Keeping Up With The Kardashians, telling partner Scott Disick: "I'm pregnant. It was not a plan," during a conversation in their walk-in closet.

Not the most enthusiastic delivery of good news we wouldn't say, though the pair have been rumoured to be on the rocks, with reports from Radar Online that Scott had moved out of their Hamptons home into a motel.

However, the pair were seen last night heading out for dinner in Southampton, hand-in-hand. So we can rest assured is all good in the Disick-Kardashian camp.
