Jeff Bezos and Lauren Sánchez Hang Out with Kim Kardashian, Lenny Kravitz and More at 2024 Oscars Party

Jeff Bezos and Lauren Sánchez had a night to remember after the Oscars on Sunday!

Bezos, 60, and Sánchez, 54, joined several other celebrities — including Kim Kardashian, Lenny Kravitz and more — at the 2024 Vanity Fair Oscar Party, which was held at the Wallis Annenberg Center for the Performing Arts in Beverly Hills, California.

Sánchez, who wore a red Lever Couture gown to the event, described the night as the “most magical evening” in a post on Instagram, which featured a behind-the-scenes look at the Emmy-award winning journalist in her luxurious attire.

She also re-shared a photo from Sofía Vergara — which included Kravitz, 59, Kardashian, 43, Kris Jenner and Demi Lovato — on her Instagram story, in which she dubbed the evening the “best night.”

Bezos and Sánchez stepped out the night prior for the Chanel and Charles Finch Annual Pre-Oscar Dinner at Beverly Hills’ Polo Lounge.

The couple got engaged in May 2023, more than four years after they went public with their relationship in January 2019. 

Bezos recently moved to South Florida after purchasing a $79 million, seven-bedroom mansion on a small private island in Biscayne Bay in September 2023. Additionally, the Amazon founder bought a neighboring home that June for $68 million.

Meanwhile, Sánchez just shared cover for her children’s book, called The Fly Who Flew to Space, which is set to hit shelves on Sept. 17.

"I've had this idea for a long time," Sánchez, 54, exclusively told PEOPLE. "But it was a little bit different when I envisioned it all those years ago. Back then it was about a fly that got stuck in a helicopter. I was actually learning to fly helicopters at the time, and it happened to me. I was like, 'Oh, look at this little fly...who's flying.'"

She also recently told PEOPLE that she will soon announce who's joining her all-female flight to space on Blue Origin soon, which she first announced in 2022.

"I'm extremely excited," she said. "We haven't announced the date yet, but it will be this year. And we'll start announcing my fellow astronauts in the coming months."
