In an unearthed clip from Keeping Up With The Kardashians, Kourtney and her baby daddy Scott Disick urged then-teen Kylie Jenner to use protection two years before she got pregnant.
Ever the caring big sister, Kourtney and her then-boyfriend were quick to warn the teen not to have unprotected sex.
Kylie, 24, welcomed her second child with boyfriend Travis Scott last month, but it has now resurfaced that her big sister told her not to get pregnant.
At the time Kylie was just 17 when she asked her sister: "You're pregnant? You're not pregnant..."
With a bobbed hairstyle which was dyed blue on the ends, Kylie looked a far cry from how we know and love her today.
After the probing question, Kourtney's then-beau replied: "Isn't she always? Bible."
"That's so funny," Kylie laughed, which led Kourtney to laugh before saying: "Scott wants to kill himself."
He then replied: "I'm gonna be happy once the little person comes but it's a lot to deal with," before urging Kylie to make sure she uses protection when she has sex.
He told the teen: "Do not have unprotected sex. You hear me? Even if you have to double up on birth control. Just do it."
Two years after the stern warning, Kylie fell pregnant with Stormi at just 19 years of age, with her and boyfriend Travis welcoming their bundle of joy in February 2018.

And at the beginning of February 2022, four years after Stormi's arrival, the music mogul gave birth to a baby boy and then announced that they had named him Wolf.
Sharing the moniker in an understated way, she uploaded a black box onto her Instagram Stories with her tot's name written in white accompanied with a white heart emoji.
Kylie did not share she became a mother for the second time until five days after Wolf's arrival.
She delighted fans when she shared a sweet black and white snap on Instagram with the caption: "2/2/22".
Kylie's mum Kris Jenner recently discussed what it was like being at the birth of Wolf.
The 66-year-old told host Ellen DeGeneres of The Ellen Show: "He's so cute," she gushed. "It's amazing I was in the hospital when he was born. It was me, Kylie, and Travis."
Kylie was first linked to Travis Scott at Coachella in April 2017.
They broke up in September 2019, but quarantined together during the coronavirus pandemic for their daughter Stormi.
While spending more time together they ended up rekindling their romance and as a result, the couple now have two children together.
