Kourtney Kardashian just gave her son a pretty great birthday gift: a little brother!
The Keeping Up with the Kardashians star and Scott Disick welcomed their third child, a boy, on Sunday, Dec. 14, PEOPLE confirms — the same day their son Mason Dash turned 5.
The new baby also joins big sister Penelope Scotland, 2.
Kardashian, 35, revealed she was having a boy on last week’s episode of Kourtney and Khloé Take the Hamptons on E!
“It’s going to be perfect for our family,” she said.
As for Mason, he still got a special birthday celebration. His famous family, including aunts Khloé Kardashian and Kendall Jenner, threw him an early Nightmare Before Christmas-themed bash in November.
