The 19-year-old cosmetics maven shared a series of steamy shots to Instagram in honor of the rapper — who was celebrating his 27th birthday on Saturday.
The two are embracing one another in an intimate pose in the shots — Tyga sitting on the floor with his back to the wall and Jenner in his lap, embracing him. Both are wearing jeans in the pics — though their shirts seem to have gone missing.
“Happy birthday baby,” Jenner captioned ones how — that showed Tyga’s head buried into her chest, and hands embracing her rear.
“Irreplaceable,” she wrote of a black-and-white photo showing the couple in a similar pose, enjoying a more light-hearted embrace.
On Friday night, Jenner took to social media with her friends to share a series of sexy pictures during some pre-birthday celebrations for Tyga.
Wearing a black spaghetti strap dress, Jenner smile in front of gold balloons that read “Happy Birthday” in one show — and posed in front of a mirror for a video shared to Instagram and Snapchat accounts.
She then headed out to a show with a group of girlfriends — though it didn’t appear Tyga was by her side.
Later, Jenner changed into a star-printed black cropped sweatshirt and black bottoms, as she hung around with her friends and sung-along on Snapchat to songs like Jeremih & Juicy J & Twista’s “Woosah,’ Bryson Tiller’s “Sorry Not Sorry,” and QUIŃ’s “Math.”
Jenner eventually debuted a custom “Happy Birthday Tyga” filter on Snapchat — featuring a cartoon creation of the happy pair.
