Sydney Sweeney throws her 28th birthday party with A-list guest list

Sydney Sweeney marked her 28th birthday with a cosmic celebration that drew some of Hollywood’s brightest stars and a global power couple.

The actress hosted her “Planet Syd” bash on Sunday night, September 28, at Vibiana in Los Angeles, transforming the venue into an outer-space fantasy.

The Euphoria star made headlines for her outfit alone, donning the glittering chainmail minidress once worn by Britney Spears in her 2008 Circus album shoot.

Amidst ongoing romance rumors, music mogul Scooter Braun was spotted at the party, mingling with guests as he and Sweeney continue to step out together.

The guest list was star-studded with co-star Glen Powell arriving in a full NASA astronaut suit, while Amazon founder Jeff Bezos and his wife Lauren Sánchez made a rare appearance, underscoring Sweeney’s reach beyond Hollywood circles.

Inside, social media snippets spotted the birthday girl dancing with rapper Sexyy Red and belting karaoke with Wiz Khalifa, keeping the energy high well into the night.

Sweeney, who officially turned 28 on September 12, has had a whirlwind year filled with blockbuster projects and high-profile campaigns, some sparking controversy but ultimately keeping her firmly in the spotlight.

Her out-of-this-world birthday served not only as a celebration but also as a reminder of her growing star power, both on and off screen.
