Aww what a little cutie!

Kourtney Kardashian gave birth to son Reign Aston Disick back in December, but we're just now getting a peek at the little guy in the reality star's first Instagram pic, and he looks exactly like his sister Penelope!

"My little turtle dove angel baby boy Reign Aston Disick," she captioned the sweet snapshot.

The Keeping Up with the Kardashians star has a lot on her plate with three young kids and partner Scott Disick going in and out of rehab. If The Lord wants to keep his lady, he should probably pull his weight around the house and help out with the child rearing. It's not cool to be a drunk, hard partying father. Get it together, LD!
