Kylie Jenner and boyfriend Timothée Chalamet had the ultimate date night following the Paris premiere of his film, 'A Complete Unknown.' See her glam and sexy outfit!

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.
