There's just a few hours left until the ultimate social experiment returns!
Big Brother is back on TV screens tonight after a five year hiatus.
The show is asking for social media users to treat the housemates with kindness.
On the show's social media accounts, host AJ Odudu says she wants this series to be the most positive series yet.
ITV1 will see a new cast of "carefully selected housemates from all walks of life" arrive at the brand-new house in front of a live studio audience at 9pm tonight.
Irish contestants that have been on the show over the years include: Hughie Maughan, Brian Dowling and Jedward.
