UK Big Brother contestant Cameron Stout is temporarily swapping places with a housemate in the African version of the show.
Cameron Stout was taken out of the house and onto a plane
Cameron, 32, from Orkney, left by plane in secret on Sunday morning.
His challenge is to deliver a message in an envelope to the Big Brother house in Randburg, South Africa.
His place in the UK house has now been taken by Ugandan law student Gaetano Kagwa, who arrived on Monday morning.
The swap, which Channel 4 bosses hope will boost ratings, is expected to last at least a few days.
When Cameron entered the reality TV show's diary room and accepted the challenge, he had no idea where he would be going.
On being told the destination, the fish trader from the Orkney Islands said: "Woo, Africa . Wowee. That's phenomenal. I can't believe it."

He will be granted a two-week amnesty from nominations, although he himself will still be able to make nominations.
Cameron was not allowed to tell his fellow housemates about the trip before he was whisked away.
Gaetano, known as Gae, lives in Kampala and has a degree in politics. He likes motorbikes, football and jazz.
