Something "new and exciting" is happening in Kylie Jenner's life, and it involves Timothée Chalamet.
A source has told ET that Kylie Jenner, who is 25, and Timothée Chalamet, who is 27, are dating.
But the person says that it's not that big of a deal right now.
Neither star has talked about the relationship in public, and they haven't been seen together in an official role.
"Kylie decided that she didn't want to make her relationship with Timothée public this past weekend at Coachella," says the source.
As for how they met, it could have been because of her sister Kendall Jenner.
