No official announcement about the twist has been made, other than a listing on the Channel 5 website, showing that next Sunday (14 June), a 90-minute live show is due to take place, dubbed ‘Big Brother: Time Warp Live Launch’.
Since the beginning of the series, it’s been rumoured that that former housemates from years gone by - such as Nikki Grahame or Nadia Almada - could be returning to the house, so speculation is now rife this might be the case.
So far, various twists in this year’s ‘Timebomb’ series have seen the contestants being thrown forwards and backwards in time, such as on the first night, when Simon Gross found himself unceremoniously evicted from the show, after just one hour in the house.
Tune in at 9pm on Channel 5 to see which of them will get the boot.
'Big Brother': Top 10 Channel 5 Housemates
Steven Goode (‘Big Brother: Power Trip’)(01 of10)
Open Image Modal
It wasn’t always easy to side with Steven during his turbulent time in the ‘Big Brother’ house, but his determination to win from the offset and fast-flourishing relationship with Kimberly made him one to keep an eye on, if nothing else.We’ll remember him most fondly for his erratic behaviour when Kimberly (now his wife) was removed from the house… oh, and for whispering “open it” to her under the covers (we’re still praying she had a packet of Maltesers under the covers).

Sara McLean (‘Big Brother 2012’)(02 of10)

An oft-overlooked housemate from the Channel 5 alum, Sara sticks in our heads mainly for the time she got drunk and performed a heartfelt and teary rendition of ‘God Save The Queen’, to publicly pledge her love for the Royal Family. (credit:Channel 5)
Harry Blake (‘Big Brother 2011’)(03 of10)

One of the stand-out housemates of Channel 5’s first ever ‘BB’ series, prank-lover Harry’s finest hour came when he blew the housemates entire shopping budget entirely on bananas. Amazing. (credit:Channel 5)
Danielle McMahon (‘Big Brother: Power Trip’)(04 of10)
Open Image Modal
Her traditional Christian values - which included being vehemently against gay marriage and abortion - made her a polarising figure in last year’s ‘Big Brother’, but there’s no denying that Danielle was a vital ingredient to making ‘Power Trip’ such an exciting series.Danielle’s rows with eventual-winner Helen Wood made for must-see viewing, with the two often ending up in shouting matches with each other over the smallest things, while her Diary Room rants frequently made for ‘BB’ comedy gold… even if that’s not quite how Danielle intended things to be.

Scott Mason (‘Big Brother 2012’)(05 of10)
Open Image Modal
Scott was a perfect example of a young person going on 'Big Brother' not to look for fame but just to get to know people he wouldn't have had the chance to in any other circumstances.We particularly enjoyed his crush on Arron, which - unfortunately for Scott - was all rather one-sided...

Lydia Louisa (‘Big Brother 2012’)(06 of10)

If there’s one thing we love here at HuffPost UK Entertainment, it’s a clunky Z-list name-drop. Lydia was evicted far too soon from her series, after a matter of days in the house, which we think is an injustice, largely because we wanted to hear more from her about how much she didn’t want to be associated with her famous fiancé… even though that’s all she talked about.Her famous fiancé - now husband - was later revealed to be… Andy Scott-Lee.

Helen Wood (‘Big Brother: Power Trip’)(07 of10)
Open Image Modal
Yes, yes, we know, we know… but whatever you think of Helen, there’s no point in pretending that she wasn’t pivotal in the most recent series of ‘Big Brother’. Immediately gaining a fast pass to the final gave Helen the opportunity to act exactly how she wanted without any consequences… and she made sure not to let that chance pass her by, eventually rowing with almost every single one of her housemates.Helen’s win last summer also made for one of the show’s most shocking moments in its entire 15-year run, proving Big Brother still has the power to shock.

Luke Anderson (‘Big Brother 2012’)(09 of10)
Open Image Modal
There are plenty of reasons to rate Luke so highly in our list of Channel 5 'BB' contestants, not least because he wanted to do the show not to gain fame or raise his public profile, but to gain "acceptance" and make people more aware of transgender issues.In a series of what essentially became a two-month long shouting match between two groups of housemates, Luke managed to keep his cool and stay away from the arguments, eventually being crowned the second ever trans 'BB' winner by the public.

Gina Rio (‘Big Brother: Secrets And Lies’)(10 of10)
Open Image Modal
Frankly, the fact that Gina didn't win her series of 'BB' is a reality TV injustice.Gina was like a latter-day Nikki Grahame, but while Nikki's tantrums were comparable to the rantings of a child, Gina's qualms were far more the complaints of a diva, and her hilarious asides helped make 'Secrets And Lies' one of the best series of 'Big Brother' ever (even if, sadly, the ratings weren't as high as they could have been).In particular, we'll always remember Gina and Dexter's life of luxury as they watched the rest of the housemates on the plasma screens, drinking champagne and making catty comments - camp, reality gold and exactly what 'BB' should be all about.
