The sky itself is no limit for billionaire Jeff Bezos and fiancée Lauren Sánchez. They have traveled into space, and expectations are just about as high for their wedding in Venice.

Both Oprah Winfrey and her best friend, journalist Gayle King, were seen in Venice for the event. Sánchez recently took a high-profile, all-women Blue Origin space trip that included King as well as singer Katy Perry.
