Kylie Jenner and Timothee Chalamet are adding to rumors about their supposed romance … because her car is in the driveway of his Bev Hills home!

The billionaire’s black Range Rover SUV pulled up to Timothee’s sprawling estate Thursday afternoon … and it’s sure to drive the internet into a frenzy.

Kylie wasn’t sightseeing either … her car pulled in from the road and drove straight up the winding driveway … in other words, she knew exactly where she was going.

Dating rumors have swirled around Kylie and Timothee recently … but there’s been no official confirmation from either side about a relationship.

Kylie and Timothee were spotted chatting each other up at Paris Fashion Week in a video that’s going viral online … but this is the first time she’s been photographed at his place.

As you know, Kylie has two kids with rapper Travis Scott, daughter Stormi and son Aire, and she’s previously been in a long-term relationship with Tyga.

Timothee’s no stranger to celeb couplings either … he’s been linked in the past to Eiza Gonzalez, Lily-Rose Depp and Lourdes Leon.

It’ll be interesting to see if Kylie and Timothee are toying with folks … or if this is the real deal.
