British singer Sarah Brightman is in talks with the space tourism firm Space Adventures to become the world's eighth space tourist, a senior Russian space official said on Wednesday.
"I think that if we do come to a consensus, then theoretically it can happen," Alexei Krasnov, head of manned space missions at the Russian space agency Roscosmos, said.
No contracts have been signed yet, he added.
If the deal goes through, Brightman, the world's bestselling classical vocalist, can become the eighth private individual - and the second woman - to make the trip to the International Space Station.
The previous tourists have paid the average of $30 million for their tickets.
