Jeff Bezos and Lauren Sanchez's superyacht engagement party reportedly included business titans and celebs, from Bill Gates and his girlfriend to Leonardo DiCaprio

• Jeff Bezos hosted a party Wednesday to celebrate his engagement to Lauren Sanchez.
• Some big names attended, including Bill Gates, Bumble CEO Whitney Wolfe Herd, and Kris Jenner.
• The party took place on Bezos' $500 million yacht, which first set sail in February. 

Jeff Bezos and Lauren Sanchez celebrated their engagement last week — and their party aboard the Amazon cofounder's $500 million superyacht attracted some big names. 

Attendees included Kris Jenner, Bumble CEO Whitney Wolfe Herd, and fashion designer Sarah Staudinger, according to photos on Sanchez's Instagram.

Bill Gates attended the party, which took place on August 2 in Positano, Italy, with his girlfriend Paula Hurd, Page Six reported, sharing paparazzi photos of the event. Wendi Murdoch, Rupert Murdoch's ex-wife, was also at the party, the photos show.

Other celebrities in attendance included businessman and super agent Ari Emanuel, who attended with his wife Staudinger, Andrew Garfield, Tobey Maguire, and Rania Al Abdullah, Queen of Jordan, according to Page Six.

Leonardo DiCaprio was reportedly also at the party, implying that he is on good terms with the couple after Bezos jokingly threatened him in November. After a video showed DiCaprio having a close conversation with Sanchez at a gala, Bezos quoted the tweet with a photo of himself standing near a steep cliff warning sign. Bezos tweeted "Come here, I want to show you something," and tagged DiCaprio. 

Insider reached out to spokespeople for the reported party guests for further comment but didn't hear back ahead of publication.

Bezos's relationship with Sanchez went public in 2019, shortly after his ex-wife Mackenzie Scott, announced she and Bezos were getting divorced. Scott's marriage to Bezos lasted 25 years and they have four children together. 

Sanchez, founder of aerial film production company Black Ops Aviation, was a news anchor for Good Day LA and has appeared in several tv shows and movies, including a small role in "Fight Club." Sanchez and Bezos reportedly got engaged in May after dating for four years. 

Bezos and Sanchez have been spending lots of time on their $500 million yacht, which first hit the seas in February. The couple has been photographed enjoying the yacht this summer, and Sanchez has also posted photos of Bezos enjoying the boat on her Instagram.
