Kourtney Kardashian posted an Instagram photo of newborn baby boy Reign Disick Monday. Well, just of his legs.

The reality TV star has yet to release an official photo of the new addition to the family but she let the world see his little feet as he wore a pair of Doc Martens.

The Kardashian sister is also showing her little Jenner sisters some love on Instagram as they walk the runway for New York Fashion Week. She posted a photo of Kylie Jenner modeling in Marc Jacobs.

Then she posted a photo of Kendall wearing a dress by the late legendary designer Oscar de la Renta for New York Fashion Week.

The beauty is "obsessed with the new Kardashian kids polka dot metallic tutu." She posted a photo of the new design along with a pair of matching metallic shoes and a headband.


She also reminisced about the days before their hit series "Keeping Up with the Kardashians" where she and Khloe were interviewed about their Dash boutique store.

Now, she is a mom of three with longtime boyfriend Scott Disick and she and her sisters are always making headlines about their daily lives or rumors about them.

Rumors are most recently saying that 19-year-old Kendall and 31-year-old Scott have hooked up but Kourtney does not believe it, according to HollywoodLife.com.

"It's not that Kourtney believes Scott and Kendall have hooked up, but it's still not a good situation," a source told HollywoodLife.com.

"All these rumors are stressful for her, they get to her because she does have huge trust issues with Scott."

The source added, "He has a wandering eye and he's a huge flirt, she knows he flirts with girls when he's out and most of them are Kendall's age so as ridiculous as this whole story is, it does open up a wound for her."

Kourtney Kardashian and Scott Disick welcomed baby Reign on Dec. 14.
