Bezos and Sánchez are not the first celebrity couple to choose Italy for their destination wedding. A hot spot for celebrity nuptials, George and Amal Clooney also wed in Venice in 2014, as did Salma Hayek and her billionaire husband François-Henri Pinault in 2009.

The wedding, hosted in Venice, Italy, is expected to cost millions of dollars as residents protest the upcoming luxury event.

Among the big names on the approximately 200-person guest list for the Bezos-Sanchez wedding are celebrities like Oprah Winfrey, Mick Jagger and Leonardo DiCaprio, as well as Katy Perry, who traveled to space alongside Sanchez on a Blue Origin flight in April, the AP notes.
