John Loughton, a 20-year-old politician from Edinburgh, has taken the £50,000 prize as the winner of E4's series Big Brother: Celebrity Hijack.
Viewers had four days to choose their favourite finalist
He got 54% of the vote in the final of the E4 show, finishing ahead of circus performer Emilia Arata, 18.
Loughton chairs the Scottish Youth Parliament and is studying for a degree in politics and sociology.
He beat 11 other "talented" young people in a series which reinvented the Celebrity Big Brother format.
Channel 4 bosses decided to change the show after last year's race row involving reality TV star Jade Goody and Bollywood actress Shilpa Shetty.
However, the new programme has not generated as much interest as the old format had done previously.
Last year's Celebrity Big Brother opened with 7.1 million viewers on Channel 4 alone.
Celebrity Hijack launched earlier this month with a combined total of 3.4 million viewers on Channel 4 and E4.
But the final edition of the show was seen by only 644,000 people on Monday, overnight estimates suggest.
Matt Lucas was the first star to act as Big Brother
This year 12 housemates were selected for their intelligence and talent while celebrities took it in turns to take over the role of Big Brother.
Little Britain's Matt Lucas was the first star to take control followed by Jimmy Carr, Joan Rivers, Brian Sewell and Ian Wright.
Loughton became the early favourite to win the show after passing a secret task set by Lucas.
He was directed through a hidden earpiece to do whatever Lucas ordered and was also made to insult his fellow housemates, dance an Irish jig, feign an attack of cramp and crawl around the house on all fours.
By passing the task Loughton earned himself a guaranteed place in the final.
Conceptual artist Amy Jackson, 21, came third and Anthony Ogogo, 19, a boxer, from Lowestoft, was fourth.
