The Celebrity Big Brother 2017 house has been hiding a big secret this whole time.

Rylan Clark-Neal revealed the unseen part of the house in last night's Bit On The Side.

The spin-off show was airing live from inside the house as friends and family of the finalists entered.

And Rylan introduced them via a secret door hidden behind a bookcase in the living area.

"Here's a little behind the scenes trick I bet you guys never knew," Rylan said, "That this was a door."

The friends and family then entered the house via the secret door where they each given 10 seconds to speak to their loved ones.

The friends and family included Derek's son, Amelia's brother, Sam's mum, Jemma's friend, Sarah's friend and Chad's sister, who appeared over the phone.

The final of Celebrity Big Brother 2017 airs live tonight on Channel 5.

After 25 days, a total of 15 housemates went through the doors but currently just 6 remain following a surprise backdoor eviction on Thursday.

It was Shaun Williamson who left in last night's show, starting a race to the final less than 24 hours away.

Those left in the house for the final are Girls Aloud star Sarah Harding, Made In Chelsea's Sam Thompson and famous TV psychic Derek Acorah.
