Big Brother USA is to air in the UK for the first time this year.

The fourth series of the show begins on July 8 in the States, where it will broadcast on TV network CBS three times a week.

Since our version of Big Brother is running until July 25, we won't pick up the US series until one day later, July 26.

The three weekly shows will air the next day on E4. The channel will also broadcast live, round-the-clock footage from the BB USA house, but on a 24-hour time delay so that the main shows make sense.
