Paris Hilton capped off summer 2025 with a blowout only she could pull off. On September 20, the heiress opened the gates of her new Beverly Hills estate, Slivington Manor, for an inaugural bash that felt part carnival, part art show, and all Paris.

The estate’s sprawling grounds transformed into a neon dreamscape, featuring installations by Insomniac, Liquid PXL, and @11d.agency. Guests roamed through oversized art pieces, snapped photos in a Parívie-branded selfie lounge, and indulged in truffle caviar and gummy bear ice cream sundaes.

At exactly 11:11 p.m., the party shifted gears. Hidden doors swung open to reveal the newest edition of Club Paris, where Hilton herself took over the DJ booth. Later, Avril Lavigne jumped onstage to perform her 2007 hit Girlfriend, cementing the night as a pop-culture time capsule.
