Tyga and Kylie were also seen hand-in-hand outside Kendall Jenner's apartment.
While the on-again, off-again couple appeared quite cozy after the AMAs, they opted not to pose together on the red carpet. Instead, Kylie stopped for photos with Kendall and model Gigi Hadid.
This isn't the first time Kylie has been spotted with Tyga since the two allegedly split. Over the weekend, she also posted a Snapchat pic of her cuddled up to the hip-hop star, writing: "Everyone needs to chill out."
Kylie admitted to ELLE Canada that she and Tyga have broken up in the past. "I don't want people to know every time we fight or break up, so I'd rather keep some things private," she said.
