In the pic posted on Friday morning by the 26-year-old rapper, Kylie is seen laughing while sitting on a bed. Tyga captioned the image: "They always come back..."
He later deleted the post.
Kylie posted a pic on her own Instagram of herself in the same dress worn in her ex's post, but made no mention that she was hanging out with him.
She later posted a new photo of herself and tagged Tyga’s Insta account, leading us to believe that they’re hanging out once again.
Tyga wasn't seen in her Snapchat story either, which included her taking a trip to In-N-Out and hanging out with her mom, Kris Jenner.
This possible reunion between Tyga and Kylie shouldn't come as a shock. Earlier this month, a source told ET that the Keeping Up With the Kardashians star wasn't serious with PartyNextDoor because she wasn't over her recent breakup.
"She's still a little sore from Tyga -- he was her first real love," the source said. "Kylie is just living her life right now and having fun."
Things looked pretty serious between PartyNextDoor and Kylie when they heavily made out in his music video for "Come and See Me." Check it out:
