Simon Webbe, Duncan James and Antony Costa entered the famous house this afternoon (25 January) to surprise their friend Lee, who has made it to the final week despite his controversial love triangle with fellow housemates Jasmine Waltz and Casey Batchelor.
The boys performed their hit single 'One Love' for the remaining seven housemates... But not one of them could dance along, clap or show any enjoyment! And when Duncan James kissed Luisa Zissman on the lips, she couldn't even protest (although we doubt she'd have wanted to!).
That's because it's all part of CBB's latest task, 'For Whom the Bell Tolls'.
In scenes to be aired tomorrow (January 26), all contestants will be visited by friends or family, but have to stay as still as a statue in order to win the task.
Ollie couldn't hold back the tears when his mum, sister and dog visited him in the garden, while Sam's mum gave her daughter a hug and said she approved of Ollie as a potential suitor!
After visiting the house, Blue couldn't resist sharing their excitement with their Twitter followers.
Simon said: "The @bbuk was so much fun today lol so good to see my brother @LeeRyanMusic today and the rest if the house @TheDappy etc."
While Duncan shared a picture of the band with Rylan Clark, host of Big Brother's Bit On The Side. He wrote: "So look who we bumped into today as well !! @Rylan !!! All will be revealed soon."
All three boys have been supporting Lee from outside the house, and urging their fans to vote to keep Lee in the house.
During last night's eviction show, Linda Nolan became the fifth housemate to be kicked out.
One more celebrity housemate will leave the house in a surprise eviction tomorrow.
