Haley Kalil let loose at the Sports Illustrated Swimsuit 2026 party in New York City on Thursday night.
The scientist-turned-content creator, who’s featured in the iconic brand’s May issue, shared some behind the scenes videos of the star-studded bash to her Instagram Story for her nearly 10 million followers.
Haley hit the dance floor with friends and was seen enjoying a performance by Fetty Wap at the Hard Rock Hotel.
Fellow SI Swimsuit models Olivia “Livvy” Dunne, Alix Earle, Jena Sims, Brooks Nader and Ilona Maher all attended.
Former SI Swimsuit cover star, Camille Kostek, who appears in this year’s issue, attended the party with boyfriend, future Hall of Fame NFL tight end Rob Gronkowski.
Sims shared a snapshot of Haley posing for a photo at the party, captioned, “Haley at work.”
The internet personality modeled a number of sultry swimsuits, including a strapless red one-piece and a cutout yellow bathing suit during her photoshoot, which took place in Loreto, Baja California Sur, Mexico.
Haley’s photoshoot took place in December, a month before she was sued by her ex-husband, former NFL player Matt Kalil, for publicly discussing intimate details about their marriage — and mentioning the size of his manhood during an appearance on a Twitch livestream in November.
The model did not specifically name the former first-round pick during her now-viral appearance on a 2025 Twitch livestream, when she graphically detailed the size of a penis as “two Coke cans, maybe even a third.”
View this post on Instagram Haley returned to the SI Swimsuit issue for the first time since 2021.
She made her SI Swimsuit debut in 2018 as a part of the first Swim Search open casting call, where she was named the co-winner alongside Camille Kostek, and went on to appear in four consecutive issues.
Haley is set to host the Netflix competition series, “Win The Mall,” premiere this fall.
