Kylie Jenner and Timothée Chalamet have been linked since around April 2023, so as of early 2026 they’ve been involved for roughly two and a half to almost three years, depending on the exact start date.

Quick timeline

  • Multiple outlets report that Kylie and Timothée first sparked romance rumors in April 2023, shortly after her split from Travis Scott.
  • They stayed low-key at first and didn’t have a major public “soft launch” until they were seen kissing at Beyoncé’s Renaissance World Tour in September 2023.
  • Coverage through 2024 and into late 2025 continues to describe them as still dating (with some tabloid breakup rumors along the way), which puts the relationship at just under or around the three‑year mark now.

So, in casual terms: Kylie has been with Timothée since spring 2023, making it an approximately three‑year relationship by early 2026.
