The big reveal!

Kourtney Kardashian welcomed her third child, a baby boy, with longtime boyfriend Scott Disick on Dec. 13., and it looks like the couple has decided on a name for their son. The reality star took to her Instagram account to share a sweet shot of her holding hands with the newborn, and revealed his name in the caption:

Madly in love with my little Reign Aston Disick.

"Madly in love with my little Reign Aston Disick," she wrote.

Kourtney Kardashian is quite the trendsetter when it comes to baby names. When she gave birth to her son Mason in 2009, the name was ranked at #34 on the list of most popular baby names for boys in the U.S. In 2013, according to Nameberry, Mason shot up to #4. Similarly, when daughter Penelope was born in 2012, it did not crack the top 100 most popular baby names for girls that year, but in 2013, Penelope came in at #56. So, those are either two big coincidences, or America really is trying to keep up with the Kardashians.
