KOURTNEY KARDASHIAN and her baby boy Mason were rushed to a Los Angeles hospital by ambulance this past Friday night after a mysterious health scare!

RadarOnline.com was there to get exclusive video and pix of the unscripted crisis and you can see it HERE!

The eleven-month-old Mason gave Kourtney and dad Scott Disick the scare of their lives as paramedics were forced to treat the tiny tot at their Hidden Hills, California, home at around 10pm.

After a few minutes inside, the responding medics decided to take Mason – who was conscious – to a nearby hospital for evaluation.

He was strapped into a gurney in the safe hands of his mother.

"Scott was terrified," an onlooker said.

"He was clearly pretty worried about whatever was going on, but Kourtney was far more in control of the situation."

Kourtney, 31,  walked out of their mansion clutching Mason, until paramedics convinced her to sit in the ambulance with the tot.

Wide-eyed, Mason watched on and seemed unfazed by all the commotion.   

Mason and his first-time mom, the star of Kourtney and Kim Take New York, were then transported to a local hospital, as father Scott followed in his Mercedes Benz sports car.
