The cosmetics mogul rocked what looked to be a semi-sheer ensemble and a dark jacket while the Astroworld artist stood behind her.
Jenner shared the pics in a slideshow on Instagram on Saturday. In one photo, Scott is rocking a shirt and black pants. In the second photo, his shirt is gone entirely, and Jenner is showing quite a bit of her legs.
"Dress up with @matthewmwilliams @givenchyofficial," Jenner captioned the pics. "This collection is wow 🤤🤤 congrats !!! can’t wait to see more."
The steamy pics come amid uncertainty as to the status of the couple's relationship. The famously on-again/off-again pair -- who began dating in 2017 -- have been keeping their romance somewhat low-key.
In March, ET learned that they had officially gotten back together after previously splitting up in October 2019.
"The couple has always had love and respect for one another but took a break last year because they both had so much going on," a source told ET at the time. "They couldn’t fully focus on what it took to make the relationship work... [and] although things haven't slowed down much for the duo, they're better able to handle it."
They have also been working hard at parenting their young daughter, especially amid the pandemic.
