Timothée Chalamet’s been surfing the fame wave like a champ over the last few years — but he’s already thinking legacy, saying he believes the whole point of life is, well … making little mini-mes.

The actor got candid in a new interview … skipping the Kylie Jenner chatter since, apparently, there wasn’t much to spill … and instead sounding off about a celeb who bragged about not having kids … which, yeah, doesn’t sit right with him.

Timothée told Vogue he watched the interview with a pal, recalling how the unnamed celeb said not having kids gave them more time to focus on themselves … something TC said is a bleak mindset to have.

The actor did note that he gets it … not everyone is able to or has the means to have kids … but he still thinks bringing life into the world is kinda the whole point of being here.

So fatherhood’s clearly on his radar … and honestly, he’s already getting a little practice in, since his GF Kylie’s got her hands full with lil Stormi and Aire.
