Watch Big Brother Season 18 Online

New series. Emma Willis ushers in another diverse group of fame-seeking individuals who have been chosen to spend their summer invading the nation's living rooms. This year, the theme is `the United Kingdom of Big Brother - and everyone is welcome'. The housemates have been chosen from a range of backgrounds for what Channel 5 is describing as the ultimate social experiment - presumably to coincide with the headline events occurring this week in the real world.
