The mum-of-three paired the tight top with jeans and heels
The star, who is currently believed to be single following her divorce from Kanye West and the end of her relationship with comedian Pete Davidson, wore a tight t-shirt with the phrase “I Love Nerds” emblazoned across it with jeans and heels.
Movie stars Chris Pratt and Jack Nicholson were also courtside on Monday night.
Last week, Kardashian and Davidson bumped into each other at the Met Ball.
They showed that there were no hard feelings as they were photographed catching up at this year’s event.
The couple dated for nine months before splitting in August 2022, and attended last year’s Met Gala together.
Kardashian and Davidson seemed deep in conversation as they were joined by singer Usher, with the mum-of-three even seen flashing a smile at one point at the swanky bash.
The annual and extremely exclusive event, which draws some of the biggest names in Hollywood and beyond, acts as fundraiser for the Metropolitan Museum of Art’s Costume Institute in New York City.
This year’s theme was announced as Karl Lagerfeld: A Line of Beauty, with Dua Lipa, Michaela Coel, Roger Federer and Penelope Cruz serving as co-chairs beside the host, Vogue editor Anna Wintour.
The theme was intended to pay homage to the late German-born fashion designer, who served as the creative director of Chanel from 1983 until his death in 2019 from pancreatic cancer aged 85.
Other VIP attendees included Brooklyn Beckham and his wife Nicola Peltz, as well as singer Rita Ora and director husband Taika Waititi.
Meanwhile, making their Met Gala debut were Brit actresses Florence Pugh, who showed off a daring new buzzcut hairstyle, and Jodie Comer.
