Big Brother 2018 starts tonight for what we now know is its final EVER series.
But exactly when does it all begin? Here's all we know about the BBUK 2018 launch this year.
When is Big Brother 2018 on TV?
Channel 5 has confirmed that Big Brother will start on Friday, September 14.
The launch will air at 9PM with host Emma Willis, running to 11:05PM. Rylan Clark-Neal will follow with Bit On The Side.
The new series will follow a few days after the end of Celebrity Big Brother, which finished on Monday
Channel 5 describe the upcoming series as having a "whole new feel", teasing: "The original social experiment, featuring housemates from all walks of life entering a new-look Big Brother House".
It's the latest launch date for a Big Brother series since 2011, when the show first moved to Channel 5.
Meanwhile, scheduling information currently puts the series at 53 days long - one shorter than last year.
As part of the launch there will be a big live twist.
Will it be the last ever Big Brother?
Channel 5 announced today that the new series will be the last EVER.
Both Big Brother and Celebrity Big Brother won't return beyond the end of the year.
In a statement, Channel 5 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."
They added: "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."
