A Cosmic Celebration

The evening was filled with spectacular décor, astronaut costumes, and a galactic vibe, attracting numerous A-list guests. For the occasion, Sweeney wore a metallic mini dress adorned with three-dimensional stars, designed by The Blonds. The form-fitting silver corset-style dress was a replica of the iconic outfit Britney Spears wore for the promotional photos of her 2008 album Circus. Sweeney even recreated Spears’ famous pose — seated with legs bent — adding a playful homage to the pop star.

She completed the look with towering heels by Italian designer Rene Caovilla, with hairstyling by Glenn Oropeza, makeup by Melissa Hernández, and styling by Molly Dickson. Through Instagram, Sweeney shared highlights of the event with her fans.

Guests in “Space Style”

Many attendees embraced the theme with creative costumes. Glenn Powell appeared as a NASA astronaut, while Lauren Sánchez wore a shimmering silver mini dress complementing Sweeney’s look. Jeff Bezos added his own touch, sporting a Blue Origin space jacket, nodding to his space exploration company.

Other guests dressed as aliens, Star Wars characters with lightsabers, and agents from Men In Black. The venue’s décor included NASA rocket models and lighting effects that gave the atmosphere a nightclub-meets-cosmic vibe.

A Birthday Trip to Mars

Sweeney celebrated her actual birthday, September 12, earlier with a trip to Utah, describing it as a “mini getaway to Mars.”
