The Sun has reported that Nick Bateman, Brian Belo and Dean O'Loughlin are among the ex-housemates who will return to Big Brother next week.
They will join BB7 star Nikki Grahame by going back into the house to perform memorable tasks from the last decade as part of the show's tenth anniversary celebrations.
'Nasty' Nick from the first series will go up against a current housemate in tackling an assault course on Monday.
Later that day, Dean from BB2 will re-enact a record breaking challenge.
Finally on Monday, three as yet unnamed housemates from BB3 will tackle an egg and spoon race. A current housemate will have to correctly guess the winner in order to pass.
Tuesday will see housemates from BB4, BB5 and BB6 go back into the house.
On Wednesday, Nikki Grahame and BB8 winner Brian Belo will each take part in a task from their year.
And finally on Thursday, BB9's Rex Newmark will return to the house to give contestants a shock, literally.
The week-long birthday celebrations will culminate on Friday July 17.
During the live show, host Davina McCall will reveal what other surprises Big Brother has in store to bring festivities to a climax live on Channel 4.

Smiles will be wiped from faces as Big Brother turns up the heat on housemates, forcing them to nominate a day earlier than normal. It is all part of a plan to shake up things inside the house, with former Big Brother housemates visiting the BB10 house over the coming week then a bunch of new housemates entering the house next Friday night. It's about to get exciting............
The Sun has reported that Nick Bateman, Brian Belo and Dean O'Loughlin are among the ex-housemates who will return to Big Brother next week.
Here are the 'Best Bits' video featuring newly evicted housemate Kris during his 37 days in the BB house. He was out of the Big Brother house with 63% of the vote in this weeks five-way battle.
The housemates were in utter shock as Davina McCall announced Kris had been evicted with 63% of the public vote in a five way battle.
It's all been kicking off in the Big Brother house over the past 24 hours. Noirin got angry because Siavash said she was like a 'rabbit', jumping between groups. That argument rumbled on and on and then boiled over again today as Halfwit got angry - in dramatic fashion.
Former housemates will be returning to the Big Brother house next week in the latest twist. To celebrate ten years of Big Brother, Nikki Grahame will enter the BB10 house on Sunday as part of a task. Other former housemates could include Nasty Nick, Craig Phillips, Brian Belo and Pete Bennett. 
Five Big Brother housemates face the public vote this week and our BBBS POLL shows you want Kris to be evicted on Friday. Do you agree or would you prefer to see the back of Marcus? Have you had enough of Halfwit? Should Dogface go? Or is Charlie the one you want to be evicted? 
Dogface almost popped out of her bikini in a wardrobe malfunction as she soaked up the sunshine in the Big Brother garden. The glam housemate laughed off the incident and managed to keep her fake boobs from popping out.
This weeks Big Brother eviction looks set to be an interesting five way contest as Marcus becomes the latest housemate to go up against Halfwit (Freddie). Thrown into the equation is Charlie, who failed a personal task for breaking rules and Dogface and Kris, who spoke about nominations.
Although nominations have yet to be announced, Charlie is to face the public vote for eviction on Friday as punishment for talking about nominations.
Here are the viewing figures for the past week's Big Brother 10:
