The brunette beauty looked amazing as she snapped away. She wore a black sports bra with the blue jeans by Khy, that were seemingly undone. She posed up a storm and snapped a few selfies, but covered her face with a black love heart emoji.

Writing on the image, Kourtney penned: "These are cute.. but...", adding on the next slide: "Do you think I can get a KB instead?" after circling the KK embroidery on the pocket of the jeans.

Back in November, it was revealed that Kourtney and her husband Travis had welcomed their first child together. Kourtney reportedly gave birth to her first baby with her husband on November 1.

It was revealed soon after that the couple had named their son Rocky Thirteen Barker. The POOSH founder has children from her previous relationship with Scott Disick; Mason, 13, Penelope, 10, and Reign, eight. Meanwhile, Travis is already dad to daughter Alabama, 17, and son Landon, 20, from his relationship with his ex Shanna Moakler.

The reality TV star also shared sensational snaps online last week as she celebrated her big birthday in the sunshine.

Kourtney showed off her flat tummy in a halterneck bikini that showed off her famous curves. "45 trips around the sun," she captioned the post. She also posted snaps of her on the dock wearing a red T-shirt with her bikini bottoms and swimming in a luxury pool.

Her glam snap was a far cry from the shot her hubby posted to celebrate her big day. Travis Barker bizarrely shared pictures of his wife Kourtney on the toilet to mark her 45th birthday.
