"They are very serious. Everyone in her family loves him," a source tells PEOPLE following the couple's PDA-filled outing at the 2025 Golden Globes

While Jenner didn’t accompany Chalamet to the A Complete Unknown premiere in Paris, continuing to keep a more or less low profile where they can, the couple shared an intimate date night straight after. They were photographed enjoying dinner at chef Cyril Lignac’s restaurant, before heading back to the elegant Hotel Royal Monceau.

Opting for a sleek look, Jenner slipped into a nondescript jet-black catsuit. As is her style DNA, the simple number still featured a risqué element. The halter neckline dipped into a low sweetheart silhouette that put her décolletage on display.

The makeup mogul “has never felt like this about anybody else before and definitely sees a future with him,” the insider says.
