The Great Gatsby star "Leonardo DiCaprio" is going to know all about space travel. The trip sitting next to DiCaprio on Sir Richard Branson's Virgin Galactic space flight went for $1.5 million at amfAR's annual gala and auction at the 2013 Cannes Film Festival. Another pair of tickets on the same flight went for $1.8 million. Branson hopes to launch the first trip from New Mexico at the end of the year. Seats on the flight go for about $200,000. That's not all DiCaprio had to offer at the star-studded event, which took place at the Hotel du Cap.
