However the two have been fitting in plenty of time watching daughter Stormi's favorite movie, a fact Kylie alluded to with a cheeky post on Saturday.
'Trolls and chill?' wrote the 22-year-old, sharing a seductive snap.
The Keeping Up With The Kardashians star bared part of her taut tummy while suggesting a movie session with her ex Travis Scott and their daughter Stormi, two.
The image comes amid renewed rumors that she and the 28-year-old rapper have reunited while living in close quarters.
Kylie was dressed sportily in a black zip-up track jacket with hypnotizing white designs over the sleeve and breast.
She paired it with black sweatpants and let her newly caramel-colored locks drape down over one shoulder
The cosmetics billionaire had one hand inside her top and raised it to reveal a bit of her tanned midriff.
She posted the flirtatious picture and caption following rumors from March that she and her quarantine partner Travis were back together.
That doesn't seem to have been the case yet, but the two have continued raising their daughter together at Kylie's mother Kris Jenner's home in Palm Springs since the start of the coronavirus pandemic.
On April 30, Kylie shared some sweet photos of Travis for his 28th birthday, most of them showing him being a committed parent to Stormi.
But the reality star also shared a steamy closeup of the former couple, with both closing their eyes and leaning their faces against each other.
'Happy birthday @travisscott!!! Stormis parents [sic]!!!!!' she captioned it.
Kylie's fans know that her daughter Stormi is a massive fan of the film Trolls and its sequel Trolls World Tour, so a rewatch of the animated jukebox musical would get a positive response.
Both her mom and dad have treated her to visits from her favorite troll, Poppy, voiced by Anna Kendrick in the movies.
On Christmas Eve last year, Travis got Poppy to come play with Stormi out in the yard, and the character made a repeat appearance for her opulent StormiWorld party celebrating her second birthday and inspired by the cover of Travis' album Astroworld.
Stormi was such a big fan of the franchise that she and her mother even got their likeness immortalized as new Trolls characters.
