The Keeping Up With The Kardashians star and boyfriend Scott Disick welcomed son Mason Dash Disick this morning.
He weighed 7lbs 6oz.
"Kourtney just delivered a healthy baby boy about an hour ago," confirmed her publicist.
The reality star's younger sister Khloe recently hinted that the birth could be any day, saying: "She could literally give birth at any second. So our cell phones are on us at all times!"
