Kylie Jenner and Travis Scott are taking a break from their relationship.
The two haven't been together publicly since his "Look Mom, I Can Fly" documentary premiered in Santa Monica on Aug. 27. They were there as a family ... with baby Stormi, but since then things have cooled.
They've been trying to make the relationship work for a while, but several weeks ago they decided to step away -- at least for now.
They were inseparable over the summer -- taking that crazy yacht trip with friends and family for Kylie's birthday. They also took a vacation together earlier this year -- in March -- after a rough patch where she thought Trav was cheating.
He was noticeably absent this weekend in South Carolina, where Kylie attended Justin and Hailey Bieber's wedding ... with Stormi.
Sources say this isn't the first time they've taken a break -- and in the past, they've managed to work it out. We're told they'll continue to co-parent, and will keep Stormi as their number 1 priority.
