The rumours about who's taking part have been rife, with names such as Christopher Biggins, Sam Fox, Lewis Bloor, Marnie Simpson, and Katie Waissel being thrown around. We won't know for definite until the night, but we're sure Big Brother has picked an explosive mix.
There's always a first-night twist on this show, so what mischief does the all-seeing eye have in store this summer? How will the stars survive?
Rylan Clark-Neal will be on hand as well to talk about the latest line up in Celebrity Big Brother's Bit On The Side after the launch show.
Celebrity Big Brother Launch Show, C5, 9pm
