The festivities began with "Unwell’s Motel 30," an exclusive two-day event held at The Breakers Motel. Friday night featured a lively party, while Saturday afternoon was reserved for recovery, as outlined in the invitations. The celebrations continued with an after-party at Common Ground, also in Montauk.

Cooper's star-studded friends, including Matt Kaplan, Leah Kateb, Maria Georgas, Hallie Batchelder, Owen Thiele, Kierra Lewis, Miguel Harichi, Phoebe Gates, and Sophia Kianni, were among the attendees. Guests enjoyed a Carbone pasta station where Mario Carbone prepared the famous Spicy Rigatoni, complimentary drinks at Big Al’s Bar, a Burt's Bees popsicle stand offering custom "Father's Bees" balms, and a Bondi Sands Pool Takeover complete with a self-tanning bar.

The event also featured a custom VW Kombi bar by Red Bull, drinks served by Sun Cruiser, a DJ set by Beau Cruz, and surf lessons.

In addition to celebrities and her husband Matt Kaplan, whom she married in April, Cooper invited fans to join the festivities.

"The Daddy Gang completely took over Motel 30, and let me tell you, it’s been so much fun," Cooper shared in a statement to People. "We’ve been living our best lives in Montauk this weekend — eating, dancing, and obviously screaming Taylor Swift songs at the top of our lungs."

She added, "Getting to hang with all of you like this? Ugh, it’s everything."

This celebration in the Hamptons follows Cooper's recent multi-year deal with SiriusXM, which includes exclusive content, events, Call Her Daddy, and more from her Unwell Audio Network. The deal is reportedly worth up to $125 million, according to Variety.

Cooper's party came after an extended European vacation and her debut as the host of Watch with Alex Cooper for NBC Sports during the 2024 Paris Olympic Games.
