It came days after the latest sighting of Jenner and Australian NBA star Simmons, 21, sent tabloids into a frenzy.
Interestingly enough, the kiss between these two comes not even a week after speculations that the KUWK star and National Basketball Association player Ben Simmons were involved romantically started going around.
Eyewitnesses tell us Kendall was hangin' with Anwar at Socialista New York for about 2 hours - kissing, cuddling and drinking with the youngest Hadid sibling the whole time.
Earlier in the night, Kendall and Anwar had been seated at the same table for the Council of Fashion Designers of America gala.
To confirm that things were definitely intimate between the two, Kendall shared a picture on her Instagram story of her hand under Anwars-with his tattoo reading, 'I love you my angel.' Was that one for Kenny, little Hadid?
So has Jenner moved on from Simmons already?
These included at the member's only DUMBO House in Brooklyn, and at Hollywood hot-spots Hyde, The Nice Guy, The Beverly Hills Hotel, and the Waldorf Astoria.
Tinashe and Kendall Jenner.
Anwar recently called it quits with actress Nicola Peltz after a year of dating.
