Kylie Jenner and her new boyfriend Timothee Chalamet showed each other lots of affection while attending the men’s singles final at the US Open in New York on Sunday.

The 25-year-old lip kit mogul and 27-year-old actor shared a steamy kiss and were seen cozying up with their arms around each other as they watched Novak Djokovic win his record 24th Grand Slam singles title after beating Russian Daniil Medvedev.

Kylie – who recently attended an intimate dinner with Timothee – was also seen tenderly running her hand through the actor’s dark curls as they carefully observed the action unfolding on the track.

The reality TV star kept it casual in a black t-shirt and a pair of black sunglasses, with her locks slightly pulled back into a loose bun.

Meanwhile, the Academy Award nominee looked sporty for the outing, wearing a gray T-shirt, black hoodie and baseball cap.

It was a busy weekend for the couple, who attended a New York Fashion Week dinner together on Friday.
