Kourtney Kardashian shows off baby bump in see-through top in first photos after announcing pregnancy with Travis Barker

KOURTNEY Kardashian has flashed her baby bump for the first time since announcing she's pregnant with her fourth child.

The reality star took to Instagram on Sunday to share a slideshow of pics showing her growing belly.

In them, Kourtney, 44, focused the camera on her stomach while donning a see-through black top.

She straddled her rocker husband, Travis Barker, 47, who looked to be playfully tapping his drumsticks against her bump.

The Poosh founder also shared other close-up shots of her cradling her belly and some from her pregnancy announcement.

She gushed in her caption: "Overwhelmed with gratitude and joy for God’s blessing and plan."

Kourtney revealed she was expecting on Friday while holding a sign from the audience of a Blink-182 concert.

It read, "Travis I'm Pregnant" - a nod to the music video of their hit song, All The Small Things, which featured an attractive groupie holding up a similar sign while rocking out to the music.

Travis is the drummer of the band and looked stunned by the news as he hopped off stage to embrace his wife.

Lead singer Mark Hoppus informed fans of what was happening as the crowd cheered with joy for the happy couple.

Fans theorized that Kourtney's family might not have known about her pregnancy prior to her announcement, given their silence on social media.

Only matriarch Kris Jenner, 67, and sisters Kim, 42, and Khloe, 38, acknowledged the reveal online, while Kendall, 27, Kylie, 25, and Rob, 36, have yet to post about the news.

Kris was even dragged by her displeased fans for not putting enough effort into her post, which included a repost of the announcement video and a handful of red-heart emojis.

However, the Kar-Jenners have been aware of Kourtney and Travis' desire to expand their brood as they have been open about their struggles to conceive.

“Travis and I want to have a baby, and so my doctor took us down this road of doing IVF,” Kourtney said in a confessional on a season two episode of their Hulu series, The Kardashians.

"It hasn't been the most amazing experience," she added.

They were undergoing the IVF process; however, an insider revealed to The U.S. Sun in December 2022 that they "took a break" despite "still trying" to have a baby.

The source said: "Travis and Kourtney would still love a baby together. They're still trying.

"She took a break from IVF, but that doesn't mean plans changed."

The insider concluded: "They're hoping to welcome a baby in the near future."

Kourtney is also a mom to sons Mason, 13, and Reign, eight, and a daughter Penelope, 10, with her ex, Scott, 40.

Meanwhile, Travis shares two teenagers: Landon, 19, and Alabama, 17, with his ex-wife, Shanna Moakler, 47.
