Davina McCall has sent an emotional message of support to Emma Willis and Rylan Clark-Neal ahead of Big Brother tonight.
It's the final of the last ever series of BBUK this evening, airing at 10PM on Channel 5.
And Davina, who hosted the original series on Channel 4, has taken to Twitter to wish the team good luck.
She said in a video message: "I'm up in Manchester filming so I can't be with you guys and I really wanted to come by and say hello. I just wanted to say good luck Emma, you are amazing and brilliant. Good luck Rylan, I know it's going to be emotional. Good luck to all the crew who work on the show."
Davina added: "I know it is going to be hard tonight but I'm sending you all so much love."
Meanwhile, Rylan said in a video posted to the official Big Brother Twitter: "I have had the best time at Big Brother. I remember watching the show growing up and always wanted to be a housemate... Big Brother's been a massive part of my life.
"I found a husband from it, I made a career from it.. it's really sad it's coming to an end for now.
"I just want to say a massive thank you to everyone who has watched the main show, Bit On The Side. We've got the best fandom and I really never ever forget this."
Rylan went on to say he "hoped" the show would be back but added: "If it's the end, thank you for everything because I genuinely don't know what I would've done without Big Brother."
Before the launch of the current series, Channel 5 announced it would be dropping the show from schedules at the end of the year.
They said: "The forthcoming series of Big Brother will be the last - of either celebrity or civilian versions - on Channel 5. We’d like to thank Endemol and all of the production team who have worked tirelessly to make the show a success.
"We’d also like to thank our brilliant presenters - Emma on Big Brother and Rylan from Bit on the Side - for their consummate professionalism, Marcus, the voice of Big Brother and all of the housemates who have created so many memorable moments.
"Most importantly, we’d like to thank fans of the show for their support over the last seven years. We look forward to giving the final series a brilliant send-off."
Programme makers Endemol said that they were hopeful of continuing the show in a new home.
They said: "Whilst disappointed not to reach an agreement with Channel 5 the decision opens up a new chapter and we are excited about future possibilities for Big Brother in the UK."
Big Brother 2018 airs at 10PM on Channel 5 this evening.
