One lucky auction bidder has managed to snag a trip to space with Leonardo DiCaprio.

The trip was offered as part of the amfAR Cinema Against AIDS charity auction and dinner at the Hotel du Cap-Eden-Roc in Antibes, France during the Cannes Film Festival. Set up by Harvey Weinstein, the package includes a trip on Sir Richard Branson's Virgin Galactic with the Great Gatsby star, according to omg!.

However, the bidder, who shelled out $1.5 million to clinch the deal, had no idea what Hollywood star they would be traveling with. The item was put up for auction as "once-in-a-lifetime trip to space with a mystery guest," according to The Hollywood Reporter.

"We're going to get someone to bid on a seat next to him," Weinstein told The Hollywood Reporter of the full deal before Thursday night's event.

The out-of-this-world trip will take place in 2014, according to the Los Angeles Times. To secure a seat on a Virgin Galactic flight, it currently costs customers a $200,000 deposit.

Other items up for auction included two more seats on the same flight (which sold for $2.3 million) and an "Oscars Experience." The Hollywood Reporter states that DiCaprio was in attendance at the event when the sale took place.
