Kylie Jenner called Cardi B's WAP video the "highlight of her career" in a sweet moment between the two on set.
Keeping Up With The Kardashian viewers got to see the pair react candidly to meeting eachother for the first time earlier this week.
As Cardi admitted to 'momager' Kris that she was "nervous" to meeting Kylie, the makeup mogul also expressed her excitement over being asked to take part.
In the clip, shown in the new series of the show, Kylie is seen showing off her incredible figure in a skin tight outfit while on set for the WAP shoot.
Excited Cardi is then seen speaking to Kris Jenner who thanks her for asking Kylie to be in the video.
Cardi replied: "I was literally praying to the lord every night."
Kris then asked: "Did you say hi to Kylie?" before the Grammy winner replies, "No not yet, I'm nervous."
But Kris quickly puts her nerves at ease and explains that Kylie is just as excited to meet her, before introducing the two.
When the pair finally meet, Cardi can be seen fangirling over Kylie and tells her "Like you don't understand, I prayed."
Kylie the said: "It's the highlight of my career."
Earlier this month Cardi B responded to the criticism she received from parent-shamers following her racy performance at the Grammy Awards.
The musician, 28, turned up the heat as she danced with fellow rapper Megan Thee Stallion, 26, to their song WAP.
The two women put on an X-rated display on the stage, as they danced on a pole and laid on a bed while intertwining their legs, with the crowd watching the saucy routine unfold.
But their dance appeared to anger parents who were watching the show, with many viewers criticising the awards show for letting their performance air.
The Federal Communications Commission (FCC) received complaints from people who tuned in to watch the show, but a spokesperson told The Wrap that the number of complaints were average for the type of event.
Cardi was also targeted by fans on her Instagram, following her feud with conservative commentator Candace Owens.
One follower asked why she doesn't allow her daughter Kulture, two, to listen to her music.
"But how is this she empowering women with her music but doesn't let her daughter listen? Don't you wanna empower your daughter also??" they asked.
In response, Cardi wrote: "I don't make music for kids I make music for adults. Parents are responsible on what their children listen too or see...I'm a very sexual person but not around my child just like every other parent should be.
"My daughter doesn't need to listen to music to be empowered neither should your children. The only way to empower your kids is by talking to them, boost their confidence and making sure they get a good education.
"I never ever said that WAP was made to empower women, I'm just a freaky person and this is not the first sex song ever made. Stop expecting celebs to raise your kids."
