Timothée Chalamet just took his romance with Kylie Jenner into the stratosphere while accepting his award at the Critics Choice Awards … dishing a special shoutout to her during his acceptance speech for Best Actor.

While accepting his award, Timmy took a moment towards the end of his speech to thank his “partner of three years” Kylie Jenner — who was seated in the audience in support of her “Marty Supreme” star boyfriend.

Chalamet thanks Jenner for their “foundation” and says “I love you. I couldn’t do this without you. Thank you from the bottom of my heart” … as the camera cuts to Kylie mouthing “I love you” back.

As we know, Timmy and Kylie have been side-by-side more than ever this weekend as TC relishes in the success of his critic-loving Christmas Day film.

TMZ obtained footage of the happy couple at the at the Palm Springs Film Festival Awards Gala Saturday night, sharing an award-winning smooch as they exit the event.

Kylie even showed off her look for the night on Instagram — a bright Marty Supreme orange dress paired with matching orange nails for the event — and eagle-eyed fans noticed Timothée had dropped a comment on her post, leaving several orange hearts and sending the internet into a frenzy.

We also got video of the couple at their table for the Palm Springs Convention Center event, taking selfies with fans and looking relaxed, happy, and totally into each other.
