Kylie Jenner and Timothée Chalamet were first romantically linked in April 2023, when reports emerged that they were casually dating and getting to know each other.

Quick Scoop

  • Multiple outlets report that Kylie and Timothée were spotted on a low-key taco date in Los Angeles around April 14, 2023, sparking dating rumors.
  • Soon after, entertainment sources said they were officially dating but keeping things casual at that stage.
  • Their public “hard launch” as a couple came months later, when they were seen kissing at Beyoncé’s Renaissance World Tour in early September 2023.

So, when did they actually start dating?

Most timelines pin the start of their romance to mid-April 2023:

  • Reports describe them as “hanging out and getting to know each other” by April 14, 2023.
  • Within days, sources confirmed they were dating, but emphasized it wasn’t serious yet.

Because neither Kylie nor Timothée has given an exact “anniversary” date, fan forums and articles generally treat April 2023 (specifically mid-April) as the point when they started dating.

Latest news & trending context

  • As of late 2025 and early 2026 coverage, they are still being discussed as an on‑again couple, with timelines updated to include red carpet appearances and award show shout‑outs.
  • Commentators often note how different this relationship seems from Kylie’s past ones, describing it as more low-key and private despite the huge media attention.

In forum and social media discussions, the consensus answer to “when did Kylie and Timothée start dating” is: they were first linked and began casually dating in April 2023.

TL;DR: They started dating (at least publicly/rumor-wise) in mid‑April 2023, then went public with PDA in September 2023.
