The show returned to Channel 5 on Thursday night (22 August), just a few days after the non-celebrity version ended with Sam Evans scooping the big prize.
But in that short space of time the whole house has been given a celebrity makeover. The only thing the same? Those cameras that will track the stars all day, every day!
There are 27 remote controlled cameras, 12 fixed cameras, five manned cameras, ten infra-red cameras, and a tower cam to provide views of the garden. Also, 57 camera mirrors! There really is nowhere to hide!
Of course, if the celebrities are a dull bunch there won't be much to capture. No worries here, though, as we reckon this summer's bunch will provide plenty of fireworks and drama.
The Only Way Is Essex star Mario Falcone will surely have plenty to chat about with fellow reality star Charlotte Crosby, who found fame on Geordie Shore. 5ive singer Abz Love could also chime in given his recent stint on Big Reunion.
Representing the Americans will be 18-year-old Courtney Stodden, who found fame in the US when she married Green Mile actor Doug Hutchison when she was 16 and he was 51, and - wait for it - Screech from Saved By The Bell!
Yep, actor Dustin Diamond has jetted to our shores to join the housemates. Since his days at Bayside High he's gone on to become a comedian, appear on US reality shows, release a memoir and direct and release his own sex tape.
Soap fans will no doubt be happy to see Bruce Jones and Vicky Entwistle in the house. Bruce played Les Battersby in Coronation Street until 2007, while Vicky played his on-screen wife Janice.
Loose Women panellist Carol McGiffin is another housemate, as is model Sophie Anderton, football player-turned-manager-turned pundit Ron Atkinson, and Pineapple Dance Studios' Louie Spence.
Rounding up the line up is TV personality Lauren Harries, who first found fame on the Wogan show, and Irish doctor Danielle Marr, who appears in a show called Dublin Wives and is clinical director of DermaFace Clinic.
