Kylie Jenner & Timothée Chalamet Kiss During Intimate Pizza Date

Timothée Chalamet and Kylie Jenner were like high school sweethearts Tuesday night … we got shots of them making out during a pizza date in L.A.

Check out the pics … the couple got shelter from the Southern California rain inside Flour Pizzeria & Cafe … and we’re told the spot locked its doors to all other customers.

The two looked so in love as they sat at the counter devouring some ‘za … and each other!

Photogs were able to grab some pretty steamy shots of the pair locking lips.
