The “Kardashians” star, 26, shared a slideshow Sunday leading with a sunbathing snap, and eagle-eyed fans noticed the professional basketball player, 25, “liked” the social media post.
Jenner returned the favor, “liking” a photo that same day of Booker playing baseball.
Multiple outlets reported last Wednesday that the duo had called it quits after two years together.
The former couple began dating in 2020 but waited until February of the following year to make their romance Instagram-official.
