If there’s one thing the KarJenners are famous for, it’s being booty-ful — and Timothée Chalamet clearly wasn’t letting that go to waste… casually turning GF Kylie Jenner’s famous assets into a very handy assist!

Check out this vid of Timothée Chalamet fully committing to the sit-uation — moments after winning the Critics Choice Award for Best Actor, he kisses Kylie, then shamelessly turns her already-perky posterior into a push-off point to bounce out of his seat.

To be fair, it was more light support than a full-on booty smash. But hey, props are props, and it’s clear Timothée leans on Kylie more ways than one — literally and emotionally… ’cause he also gave her a sweet “love you” shout-out during his acceptance speech.
