Emma Willis took over hosting of the series for this series, and looked stunning in a little dark blue dress on the first live show tonight.
Emma introduced the latest batch of housemates to us, and a twist or two!
First in the house were twins Jack and Joe, followed by firebreathing glamour model Sallie Axl.
Self-confessed gold digger Jemima Slade was next, together with Postman Michael... who is really Big Brother's mole!.
Hunky Callumn Knell was next into the house, along with lesbian fisherwoman Wolfy Millington and stockroom assistant Sam, who reckons he's a looker for Harry Styles!
Secret karate expert Sophie Lawrence was into the house shortly after, before the final housemate of night - Dexter - completed the line up.
Then Big Brother took control of Michael Mole for the first time!
Big Brother continues with the second half of the live launch tomorrow (Friday) night at 9PM on Channel 5.
