Kourtney Kardashian and Scott Disick just gave their son Mason the best birthday present - a baby brother!
The couple, who are also parents to two-year-old Penelope, welcomed their third child together on Sunday, the same day that Mason turned five.
"The family is freaking out with joy," a source told E! News. "What an amazing coincidence."
There are no details on the new arrival's name just yet. In October, Kourtney told E! she had "some ideas" but she was waiting to meet him first.
"I want to wait until the baby is born," she added.
On Sunday morning, Kourtney took to Instagram to share a picture of her baby's crib.
Shortly after the birth, she wished her eldest child Mason a very happy birthday.
"Happy birthday to the coolest little boy in the entire world," she wrote. "You teach me so much every single day and changed my universe the second I met you. You have taught me what life is all about and I am truly blessed and honored to be your mommy."
Let's just hope he's ok with sharing his birthday from now on.
