Former Apprentice candidate James Hill has won Celebrity Big Brother, beating American Austin Armacost, best known for being the ex-boyfriend of designer Marc Jacobs, into second place.
The 27-year-old, who finished in ninth place during the 2014 run of BBC One's business series, looked shocked when presenter Emma Willis announced he had won the Channel 5 show.
He hugged the man who had been his best friend in the house before exclaiming: "Omigod! Omigod!"
It was particularly apt that the final two in this UK vs USA-themed series were a Briton and an American. Runner-up Armacost was magnanimous in defeat, telling Hill: "I love you, brother."
During his interview with Willis, Hill seemed bemused to be crowned champion. "Wow! I can't believe it!" he repeatedly said.
When asked why he thought he had won, he said: "I've been myself from the beginning. I just tried to stay grounded."
However, his friendship with Armacost was a constant theme. "I got close to some people in there that I hope I'll be close to for the rest of my life," he stated.
The 27-year-old left the house to cheers and gushed his adoration for the winner to a glamorous-looking Willis. "We've shared a bed together since day one," he said.
Viewers were captivated by the bromance between straight contestant Hill and gay housemate Armacost; it proved a popular topic of discussion as the duo shared everything from cuddles to a bed.
Celebrities from both sides of the pond battled for supremacy, but notably absent from proceedings was Teen Mom US star Farrah Abraham, following her altercation with former Big Brother housemate Aisleyne Horgan-Wallace on sister show Celebrity Big Brother's Bit On The Side.
The final produced one shock as Atomic Kitten's Natasha Hamilton, previously the bookies' favourite to win, ended up in third place.
The 33-year-old told host Willis the Big Brother house was "like being in a pressure cooker that could explode at any moment".
Comedian Bobby Davro was greeted with chants of "Bobby! Bobby! Bobby!" as he took the walk down the steps in fourth position. "I would have liked to have made top three, but I'm not complaining," the funnyman said.
During his exit interview, Willis approached the subject of US star Abraham as the pair had frequently clashed: "She's a particularly nasty person beneath that beautiful exterior. She's got to work on that."
However, an upbeat Bobby basked in the glow of his Big Brother experience: "There's no grudge against any of them, including Jenna and Farrah. They just had trouble adapting to our culture and sense of humour," the 57-year-old observed.
There were some boos when presenter Willis announced engaged X Factor couple Stevi Ritchie and Chloe-Jasmine Whichello (who count as one) in fifth spot. But Ritchie said they hadn't expected to get to the final in the first place.
"We were so full of nerves and worried about our relationship the whole time," his fiance added.
Responding to a suggestion that some didn't buy into their relationship, Whichello hit back: "We're not for sale, Emma." The 24-year-old blonde admitted: "Some aspects of our relationship we had to keep a lid on, which was incredibly difficult."
Loose Women's Sherrie Hewson ended up in sixth place. Dressed in a cream gown, she told Willis: "I've had the most fantastic time, but it's been an emotional rollercoaster."
During the controversial series, glamour model Tila Tequila was removed from the house after only one day when it emerged she had made a series of anti-semitic remarks on social media.
The other stars who took part were: US actor Daniel Baldwin, The Bill actor Chris Ellison, presenter Gail Porter, US hip hop artist Fatman Scoop, US ex-adult performer Jenna Jameson and US supermodel Janice Dickinson.
There was also the bizarre spectacle of Diana, Princess of Wales's former butler Paul Burrell spending four days inside the house; he revealed that the only time the Queen carries money is for the collection box when she attends church.
However, the biggest talking point remains the Celebrity Big Brother Bit On The Side brawl. Police are investigating the row at Elstree Studios in north London between Abraham and Horgan-Wallace which saw 'Allo 'Allo actress Vicki Michelle caught in the crossfire.
