Kylie Jenner, mother of Travis Scott's children, is rumored to be dating Dune star and pretty boy  Timothée Chalamet.

Sources say LaFlame is not happy with the arrangement.

"Travis is not thrilled about Kylie moving on, but they are still cordial and focused on co-parenting and being the best parents they can be, a source told E!

According to another source, things are still casual between Jenner and Chalemet.

"Kylie and Timothée are casually seeing each other, but are trying to keep it low-key," the source says. "They are becoming more comfortable with each other, but Kylie wants to take things day by day and see where it goes. Her family thinks it's great that Kylie is doing her thing and they are supportive."

So it's possible Kylie will be back for more breeding.
