USA TODAY reporters on the scene spotted Jenner stroking Chalamet’s chest; the pair were also caught on camera looking deeply into each other’s eyes.
They’ve also been photographed at events like the U.S. Open Men’s Final and Beyoncé’s birthday concert last year.
At the U.S. Open, Jenner sported a black T-shirt and matching sunglasses with a cocktail of Grey Goose Honey Deuce in hand, while Chalamet wore a dark gray tee with a black hoodie and sunglasses.
In one photo, Jenner can be seen appearing to whisper something in Chalamet’s ear during the game, while in another, the pair intently watch the tournament with other spectators.
