Big Brother contestant Lisa Jeynes has become the latest person to be evicted from the TV show but in a twist, former housemate Jon Tickle has been voted back into the house.
Jon cannot win Big Brother
Lisa, 35, from Penarth, near Cardiff, was voted out after spending just two weeks in the house having failed to bond with other housemates after her late introduction.
But Big Brother bosses sprung a surprise by announcing one of the evicted housemates would be going back in.
Viewers then voted for 29-year-old Jon, a data strategy manager from Staines, to go back in for the remaining two weeks of the show.
He will not be allowed to win - but he said he would not let on to the other housemates that this was the case.
"It's going to be a new Jon in there," he told presenter Davina McCall as he made his way back to the house.
"People are not going to recognise me. For two weeks I'm going to be completely different character. I'm going to mix it up... they need stirring
He added that he now realised all the "mind games" going on in the house.
His re-entry caused shockwaves among the contestants as they realised he knew what they had said about him, although he is not allowed to divulge details of happenings outside the house.
As Lisa left the house she was booed by the crowd waiting outside the Elstree studio, but she told Davina that she had "expected" that reaction.
She also said she believed she had been nominated because she was "too strong and a bit of a threat" to the other contestants.
She had been nominated alongside Cameron Stout, 32, a fish trader from the Orkney Islands and Stephanie Coldicutt, 28, a visual merchandiser from Birmingham.
Bookmaker Ladbrokes has already paid out on Lisa's eviction, having closed the book when her leaving the house was priced at odds of 1/33.
Lisa did not endear herself to fellow housemates
It is the first time bookmakers have paid out early in the history of the TV show, which follows contestants around the house 24 hours a day, allowing the public to choose who is evicted.
Jon became a favourite with fans because of his eccentric ways and wacky inventions, although he was dubbed "boring" by the media because of his love of sci-fi.
He was criticised by his fellow housemates for his constant moaning about Big Brother and continually found himself nominated for eviction.
