There was no mistaking that baby bump-Kourtney Kardashian was spotted at a recent event at the Hamptons with her longtime beau Scott Disick.

With her third baby on the way, the "Keeping Up With the Kardashians" star wowed the crowd with her plunging, short-sleeved jumpsuit made of white lace that perfectly cradled her baby bump.

Kardashian and Disick attended the "Party Under The Stars" hosted by Women's Health magazine for the benefit of RUN10 FEED10 at the Bridgehampton Tennis and Surf Club last Saturday.

The 35-year-old star looked bright and beautiful with her light makeup and naturally glowing complexion along with her long dark brown hair styled straight. Her 31-year-old boyfriend sported a more casual ensemble with a gray T-shirt, flannel shirt, and black trousers.

Disick's tanned complexion looked as if he had been catching some rays while shooting the upcoming reality show "Kourtney and Khloe Take The Hamptons".

The couple, who have two children (four-year-old Mason and two-year-old Penelope) seemed to be enjoying the event over the weekend after reportedly experiencing relationship problems.

Last month, it was reported by TMZ that Disick sought to give up alcohol to settle his troubles with Kardashian.  

In response, the reality star kicked him out of their Southampton rental house when Disick arrived home "intoxicated" and made a scene at a family gathering after a night of hard partying.

Kardashian described him as "sloppy" while sister Kim jumped to the rescue and explained how Disick can be "really unpredictable" every time he downs a lot of booze.

Disick's aunt Aundrey Martone attributed his hard partying to grieving over his parents' recent deaths. His mother Bonnie died at the age of 63 in November of 2013 while her husband Jeffrey passed away three months later at the same age.

Martone explained, "Everyone has their own way of grieving, and I respect that."
