Kylie Jenner and her new boyfriend Timothee Chalamet showed plenty of affection for each other as they attended the men’s singles final at the US Open in New York on Sunday.

The 25-year-old Lipkit mogul and the 27-year-old actor shared a steamy kiss and cuddled with their arms wrapped around each other as they watched Novak Djokovic win his record 24th Grand Slam title after defeating Russia’s Daniil Medvedev .

Kylie, who recently attended an intimate dinner with Timothee, was also seen tenderly running a hand through the actor’s dark locks as they carefully watched the action on the court.

The reality TV star kept it casual in a black T-shirt and black sunglasses, her tresses lightly pulled back into a loose bun.

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

Kylie and Timothee weren’t the only stars in attendance at the game, as Nicole Kidman, Justin Timberlake and Leo DiCaprio were all spotted at Arthur Ashe Stadium in Queens.

Timberlake – one of the world’s best-selling music artists with over 88 million records sold – looked dapper in a green and white checked shirt and khakis as he sat relatively close to the pitch. To complete his look, he also wore a brown leather strap watch with a gold frame.

Kidman, meanwhile, sat in a box next to her husband and singer Keith Urban, wearing her own striped button-down shirt over a beige top. The couple, who have two children, looked very much in love as they held hands and watched what was happening on the court.

Urban even approached his wife’s ear to briefly tell her something secret in front of the cameras while showing off a light purple button-down shirt.

Also sitting high up in a box was American model Emily Ratajkowski, who despite the rainy New York weather wore a gray dress while also wearing black sunglasses and high boots
