The POOSH founder, 44, looked stunning in a skintight pastel blue bodysuit with sheer pants and a matching sarong as she stood at the edge of her swimming pool.
Travis, 47, appeared in several shots, all of which showed him holding onto his pregnant wife.
The couple — who wed in May 2022 — recently revealed that they are expecting a son.
Despite already being a mother-of-three, Kourtney hasn’t been shy about turning to fans and the internet for pregnancy advice this go around.
On Wednesday, the reality TV star shared screenshots of her recent Google search history — all of which pertained to pregnancy insomnia.
The search engine suggested that eating a snack, taking a warm bath and/or reading a book before bed are among the best ways to ‘cope’ with insomnia.
She also looked up ‘top tips’ on how to get a better night’s sleep, which included cutting caffeine, getting exercise and/or utilizing a pregnancy pillow.
Kourtney told her 223million followers on Instagram that she’s already tried all of the methods on Google.
‘I already do this [SMILING EMOJI] what else?’ she asked.
Just last week, Kourtney asked fans to share their ‘favorite clean body care for during pregnancy?’
Kourtney was last pregnant in 2014 with her now eight-year-old son Reign, who is one of the three children she shares with ex-boyfriend Scott Disick, 39.
She is also mother to son Mason, 13, and daughter Penelope, 11.
Meanwhile, Travis and his ex-wife Shanna Moakler, 48, share son Landon, 19, and daughter Alabama, 17.
Kourtney made her pregnancy announcement on Friday, June 16 during Blink-182’s concert in Los Angeles.
As Travis performed, she held up a large sign that read: ‘Travis, I’m Pregnant.’ It was referencing to the band’s 1999 music video titled, All The Small Things.
After seeing the sign, Travis jumped down off the stage and went over to kiss his wife.
Though it was presented as a ‘surprise,’ Travis’ ex Shanna claims she’s known about the pregnancy for ‘weeks.’
Since the announcement, Kourtney has been using Instagram to show off her growing belly as well as to share milestones.
Last weekend, the couple threw a lavish gender reveal party at their sprawling Calabasas home that was rock ‘n’ roll themed.
They made the reveal by playing a drum roll which then prompted blue streamers to launch high into the air to reveal that the pair are expecting a baby boy.
Kourtney let fans in on the news by sharing a video of the special moment to Instagram, which showed her sitting on Travis’ lap as he drummed.
Their baby was conceived naturally after stopping their IVF journey over a year ago due to the effects it was having on Kourtney’s health.
She recently revealed on The Kardashians that she had previously frozen her eggs.
‘When I was 38 or 39 everyone was like pushing me to do that and most of mine didn’t survive the thaw because eggs are one cell and none of them made it to an embryo,’ she told viewers.
Kourtney and Travis became romantically involved in late 2020 after nearly a decade of friendship.
They made their relationship Instagram official in February 2021 and were engaged by that October.
The couple wed at a courthouse in Santa Barbara in May 2022 before jetting off to Portofino, Italy a week later to hold a lavish wedding at the Dolce & Gabbana mansion in front of their friends and family.
