Jenner and Chalamet were first linked in April 2023, when they were spotted together at the Jean Paul Gaultier show in Paris. They were later seen on a few other occasions, and it was confirmed in May that they were dating.
The couple kept their relationship relatively low-key, but they did make a few public appearances together. In June, Jenner was seen leaving Chalamet's house, and they were also photographed together at a party in July.
However, it seems that things have fizzled out between the two. A source told Life & Style that Jenner is "telling people that things between them naturally fizzled out because they're both busy and traveling." The source also said that Jenner's friends are "whispering that Kylie got dumped."
Other sources have said that the split was mutual, and that both Jenner and Chalamet are "sad" about it. However, they both seem to be moving on. Jenner has been spending time with her family and friends, and Chalamet has been working on his upcoming film, "Wonka."
It's unclear why Jenner and Chalamet broke up, but it's clear that they are both moving on. Only time will tell if they will ever reconcile.
