This year's Big Brother promises to be "the ultimate social experiment" when it launches next Monday.
Describing Big Brother 18 as a "must-watch culture clash of modern Britain," Channel 5 previously teased: "At a time of political upheaval and tough questions about unity in the UK, Big Brother brings you an alternative look at Britain."
They continued: "Standby for a very British summer of contrasts, conflicts and collaboration...and more fireworks than you could imagine, as a selection of people, from a range of backgrounds, come together in the ultimate social experiment.
"The United Kingdom of Big Brother…and everyone is welcome."
In a new video today, Emma introduces the new series and her hopes of a real diverse line up of housemates.
"It's the United Kingdom of Big Brother and anybody is welcome, that incudes housemates and viewers so join us on launch night," says Emma.
Speaking of this year's cast recently, Emma revealed: "The housemates will be from all walks of life and a real cross section of people from across the country, which sounds like the perfect house to me - all ages, all backgrounds.
"It should bring some very interesting situations. I love the psychological experiment aspect to it and I think having all sorts of different ages and backgrounds there lends itself well to the original idea of the show. I can't wait!"
Yesterday saw the first six housemates revealed ahead of launch, only the second time in BBUK history names have been announced before they enter.
Emma Willis will host the LIVE Big Brother launch on Monday night, June 5, from 8:30PM.
