Travis appeared at the packed festival in his hometown of Houston, Texas and several videos of the concert surfaced where the rapper made a point to call out the mother of his daughter who was in the crowd.
Jenner was spotted earlier in the day, at the festival, with the couple's young daughter Stormi exiting the backstage area with her security team.
This is an important moment for two reasons.
One, Kylie and Travis have been broken up for weeks and are trying to co-parent their daughter.
Kylie And Drake?
As we reported, Kylie made an appearance at Drake's Halloween party at Delilah in West Hollywood, which was also attended by Kylie's BFF and her bro Rob Kardashian.
Kylie was spotted drinking inside the club, but it's unclear if she and Drake had any moments inside the club.
Rumors swirled about the two, earlier in the week after Kylie made an appearance at Drake's 33rd birthday party.
Obviously, it is weird considering Drizzy and Travis Scott's released the hit single, "Sicko Mode."
Travis Says Kylie Is His 'Wife'
The video, captured by several fans gave a very emotional speech about his musical and life journey. He thanked his fans and other people who helped him along the way, including Kylie.
Scott posted a picture of a floral arrangement, earlier the same day, that spelled out the name of his festival. It seems the gift came from Jenner.
“Love u that I really do,” Scott captained the photo including a butterfly and heart emojis.
We broke the story, Kylie and Travis split after the couple simply drifted apart. We're told they were committed to co-parenting their daughter.
The Break-Up Details...
At the time, we were told they have had broke up several times in the past, and some believed this may just be a temporary split.
The couple has been living apart, with Kylie and Stormi living in the make-up mogul's Calabasas home and Travis living in his house in the Hollywood Hills.
Interestingly, leading up to the festival, Kylie and Travis have been seen together several times. But, it was unclear if they were spending time together with Stormi or if they were possibly getting back together.
A source close to the couple tells us, "It's not if they will get back together, it's when."
Fans of the couple agree with several posting they believe the separation is over, "Sooooo... about this separation then? Asking for myself," one person wrote.
"Please get back together I love them together," another commented.
Several hoping for the reunion, "I want them to make it!"
The festival was also a family affair after fans were treated to an appearance by Kanye West. Scott and West tore up the stage performing a few hits.
Astroworld was a huge success and videos from the event show just how huge the crowd was for Scott's headlining performance.
