Former LSU gymnast and social media star Olivia “Livvy” Dunne was back in the Hamptons for Fanatics founder Michael Rubin’s white party Wednesday.
Dunne, 23, was spotted at the glamorous shindig at Rubin’s Bridgehampton mansion on the east end of Long Island and shared some snaps of her at the party on Thursday.
Dunne wore a white maxi dress and matching white heels to the blowout, and her Instagram post showed her posing with a number of glammed-up pals.
In one snap, Dunne posed for a poolside pic with Olympic speed skating champion Jutta Leerdam. In another, she was with signer Tate McRae and Fanatics exec Mike Hermalyn.
And in another that she posted on Instagram, Dunne is seen hanging out with Olympic gymnast Sunisa Lee.
Dunne, who is the girlfriend of 2025 National League Cy Young winner Paul Skenes, also posted a video of her showing off her white dress before the party in a post on TikTok, which she captioned “white party” along with a heart emoji.
The annual party hosted by Rubin has become one of the hottest tickets of the summer, with some of the biggest names in sports, Hollywood and social media in attendance.

Kim Kardashian, Justin Bieber, Leonardo DiCaprio and Tobey Maguire have been among the names at past parties.
Dunne went to the Hamptons bash by herself with her baseball-playing beau on the mound for the Pirates on Wednesday night, when the party took place.
It was a tough night for Skenes as he pitched for just four innings in a 10-6 loss to the Phillies, as he gave up a season-high seven earned runs on six hits. Skenes allowed two home runs and struck out five.
Dunne made headlines earlier in the week after she took to her social media to lambast people stalking her in airports during her travels.
