Jaden, however, is friends with Kendall Jenner and not only have they been spotted hanging out together, which almost certainly means there's no bad blood between he and Kylie, but he's also been at some family stuff, like Kris Jenner's 60th birthday party and was totally cool with the Kardashian crew during Olivier Rousteing's birthday party in October.
So, when Kylie and Jaden bumped into each other at Art Basel in Miami this week, not only was it totally no big deal, they actually seemed to chat and be having a good time, as friends do (photo here).
It sounds like these two not only have a lot of respect for each other, but Kylie also has a lot of respect for Jaden and Sarah's relationship - so before any relationship rumors get started...yes, Kylie and Jaden are JUST friends.
"Kylie knows Jaden is very into Sarah and respects it and likes her as well," a source exclusively told E! News. "Jaden and Kylie are still really good friends and that is it. They will always care for each other but at this point in their lives, they just want each other to be happy."
And it sounds like things are going really well for Jaden and Sarah, too. "Jaden and Sarah are really in love with each other," their source continued. "They enjoy many of the same things. Their friends love them together. Jaden loves her style and easy going personality."
Sarah was in Miami, too, and got to see her main man perform at the event on Saturday.
