Kourtney Kardashian and Scott Disick make some pretty adorable babies.

The eldest Kardashian sister, 35, revealed her son Reign Aston Disick's face for the first time in this super-cute Instagram pic she posted on Thursday, in which he's clad in a plain white button-up onesie.

"My little turtle dove angel baby boy Reign Aston Disick," she wrote.

Kourtney welcomed baby Reign, her third child with her longtime love Scott, on Dec. 14. He joins older siblings Mason, 5, and Penelope, 2.

Previously, Kourtney has only chosen to show off Reign's already amazing newborn style, like this zippered navy-blue onesie and baby Doc Martens he rocked last month.

And just three months after giving birth, Kourtney had already shed the baby weight. Three weeks ago, she shared that she's back down to 120 pounds.

"First day that I have seen this number in a while," the mother of three posted with a picture of a scale, along with some excited emojis.

But one star apparently not that concerned with getting her pre-baby body back is Olivia Wilde -- though it's safe to say it's pretty perfect already. Olivia gave birth to her first child, Otis Alexander Sudeikis, last April.

"I am not in perfect shape," she recently claimed to Shape magazine. "In fact, I'm softer than I've ever been, including that unfortunate semester in high school when I simultaneously discovered Krispy Kreme and pot."
