See the Star-Studded Photos From Vanity Fair and TikTok's Young Hollywood Party

It was a star-studded affair at Vanity Fair and TikTok's Vanities party in Los Angeles on Wednesday night. It seemed like almost everyone in young Hollywood was in attendance, from Halle Bailey to Julia Garner to Lucien Laviscount. Paul Mescal brought his younger siblings, Donnacha and Nell Mescal, as his dates, and Lukas Gage was joined by Chris Appleton after recently addressing dating rumors.

While speaking with the New York Times in March, Gage discussed whether the recent vacation photos of him and Appleton in Mexico were a hard-launch for their rumored romance. "If they want to think that, they can," he said. "I'm a pretty open book about most things in my life, but I have a problem with the culture of everyone needing to know everybody's business and nothing can be sacred. It's a weird line that I'm still trying to figure out."

Meanwhile, "Pretty Little Liars: Original Sin" star Bailee Madison hit the red carpet with boyfriend Blake Richardson and later linked up with pals Olivia Holt and Emma Kenney. Other celebrity couples included "Outer Banks" actor Madison Bailey and Mariah Linney and Alex Lee-Aillón and Paris Brosnan.

But there were so many more celebrities who stepped out for the bash — keep reading to see the pictures!
