In an unprecedented move by Channel 5 the 16 people set to enter the Big Brother house this week have been revealed ahead of time.

Although the contestants in the reality TV show who will be filmed around-the-clock are all unknowns you might recognise a former X Factor contestant, Eileen Daly, 51, from London, and model Aaron Frew, 24, from Northampton.

Rylan Clark and Emma Willis remain as presenters on the show, now called Big Brother: Timebomb, which is in its 17 series.

Channel 5 announced last might it has signed up for at least another three years of the show.

The station said it would continue to show one series of Big Brother every year along with two series of the celebrity spin-off version.

The show, originally broadcast in the UK on Channel 4, has been a huge success for Channel 5 and guarantees them big audiences as well as a steady stream of controversy.

The main Big Brother series was the most-complained-about show of last year, with Ofcom receiving 3,784 complaints, many centred on the behaviour of its eventual winner Helen Wood, who was accused of bullying other contestants.

The previous series of Celebrity Big Brother was second, with 1,874 people contacting the watchdog.

This year’s Big Brother house is said to have been inspired by 1960s glamour of TV drama Mad Men and will include a round sofa and giant fish tank.
