The young billionaire kept up with her big sister going shot for shot as part of her “Get Ready With Me” YouTube segments.
A behind the scenes look Kylie shared showed the sisters bickering over how many shots they were actually on.
As Khloé held the liquor bottle to her lips, she shouted, “You were always ahead of me so I’ve taken 5.”
“I just took 5” she stated to Kylie. “YOU took 5, so now I’m about to take 6.”
That’s when Kylie interrupted her big sister and told fans, “Okay. We’ve BOTH taken 5 shots. We’re about to film the drunk ‘Get Ready With Me.'”
She then teased, “Stay tuned for the reveal.”
Kylie and Khloé appear in full makeup and white tees.
Wearing their hair straight with pink clips keeping their luscious locks out of their face, it appears the tanned sisters had a wild and entertaining day of filming.
Earlier in the day, Khloé Kardashian showcased her flat abs.
Wearing a crop top branding Kylie’s skincare line and Scott Disick‘s Talentless clothing company, the mom of one flaunted her fit stomach 15 months after giving birth to her daughter with Tristan Thompson.
Kylie has been 21 for almost one full year.
The youngest sibling in the KarJenner clan will turn double deuces on August 10.
Kylie’s 21st birthday was full of A-listers and booze.
There was also an unfortunate incident involving YouTube star Tammy Hembrow, who was taken out of the party by stretcher and sent to the hospital.
