The Timebomb twist for Big Brother 2015 could see housemates, tasks and twists from past series make a comeback.
At least that's according to Bit On The Side host Rylan Clark who has revealed more details about the upcoming show.
He reckons that the Timebomb theme for this summer's Big Brother could make some housemates "crack up".
"For this series, they’re flipping time on its head so they’re really going to crack up. Big Brother could make 4am the new 3pm," he teased. “It’s a little bit Truman Show — we will control the pattern of life."
Rylan explained how the show may take both housemates and viewers back in time to the BB series of years past, including the return of some former housemates.
The former X Factor star explained: "We can also visit the past so they might wake up and it be Big Brother 2007 or we go back two years and I’m suddenly a housemate again for a few days.
“Nikki Grahame, Makosi ... what’s to say they never actually left ... and could be there. It’s creepy.”
Speaking in the trailer for the new series, main show host Emma Willis said previously: "Days will turn into nights, time will stop, rewind, tasks will be turned on their heads."
