The pair were photographed together at the premiere of Scott's Netflix documentary "Look Mom I Can Fly" in late August, after appearing to be inseparable all summer.
This past weekend, Jenner attended Justin and Hailey Bieber's second wedding ceremony in SC solo.
"They are both extremely busy with different schedules and since Kylie found out about Travis messaging another girl on Instagram, the rebuilding of trust has been hard", the source claims. Clues that the now former-couple were no longer a thing began to pop up as Kylie was noticeably solo at Justin and Hailey Bieber's wedding in SC over the weekend.
The only rough patch the couple faced was back in March when Kylie accused Travis of cheating on her.
We may need to double-check a Kris Jenner bot wasn't behind that last comment, LOLz.
"Kylie Jenner was always the one showing you love, you never truly loved her, I hope you find a girl like her because you don't deserve her..."
They added that their 1.5 year old daughter is their "number one priority". An insider told E!
But, in all seriousness, these are just a few of the spirited pleas for Stormi Webster's parents to reconcile their differences.
The news comes just two months after the couple celebrated Kylie's 22nd birthday on a lavish yacht tour of the Mediterranean with her family and friends.
Aside from the lack of public outings, Jenner hasn't posted anything on her social media accounts, including the father of her child.
