It's the live launch tonight as the new batch of housemates enter the most famous house in Britain. For the first time in the show's history, we know who the contestants are already.
We've got a Calvin Klein model, an aspiring politician, an eccentric rich kid and a former X Factor hopeful. There's also a devout Christian, a set of twins who've appeared briefly in TOWIE, and an ex-pro basketball player.
As BB promises to control every move the housemates make over the coming weeks, it's set to be a series full of surprises – both nasty and nice.
Big Brother: Timebomb, C5, 9pm
