But one contestant, teaching assistant Keri Hasset from Birmingham, said she was "heartbroken" by the prank.

"When I thought we were coming back to Earth I was planning my speech. I was going to say it had been my childhood dream. Now I'm a little bit heartbroken," she said.

Any guys out there willing to 'console' this gullible babe?

On discovering the show was a fake, Billy told Channel 4: "My mum and dad are gonna love this.

"This is the biggest wind-up ever. This is wicked."

"Aw man," said Paul. "We're not astronauts. We're just asses."
