Cannes, May 24 : Actor Leonardo DiCaprio auctioned here a ticket for Virgin Galactic space trip 2015 for an international non-profit organisation that supports AIDS research.

The 39-year old auctioned off a ticket to board one of the first commercial flights into space, for an organisation that supports amFAR, reports contactmusic. com.

The person, who won the bidding war has not yet been identified, but he will now be joining the actor on a Virgin Galactic space trip in 2015.

Actress Sharon Stone, chair of amFAR, served as this year's auctioneer at the annual event held at hotel du Cap-Eden-Roc. The fundraiser event raised $35 million.

The actress predicted that by 2020, a vaccine would exist for HIV/AIDS.

"Today is the day we can say we have a cure for pediatric AIDS. There were many times, when we came here over the years where we're failing. Now we are in the beginning of the end of AIDS," Stone told the A-list audience.(IANS)
