Big Brother's Bit On The Side will take place live INSIDE the house on Monday.
There's currently just days to go before the final of Big Brother 2016 and Monday evening will see the housemates get quite the surprise.
They'll be locked outside in the garden for the evening while Rylan Clark hosts a live episode of Bit On The Side in the living area.
Rylan tweeted: "On Monday #BBBOTS will be coming to you LIVE FROM THE BIG BROTHER HOUSE 11pm @bbuk xxxxx"
The show will be complete with audience and celebrity panel, as the housemates watch on.
And Monday's show will be particularly special as it will feature the two evictees who left in Sunday night's shock eviction.
Big Brother revealed last night that lines to vote for the winner will freeze at 3PM on Sunday and the two housemates with the fewest votes at that point will leave then and there, with no exit interview, live show or fanfare.
It's one last cruel twist for the housemates who have been led to believe they're all in the final.
The two who go will join Rylan back inside the house for Bit On The Side on Monday night.
For now, Big Brother continues nightly on Channel 5 ahead of the final on Tuesday.
