With the line up now fully confirmed, who is your early Celebrity Big Brother 2017 favourite?
Tuesday was the live launch of the special All Stars v New Stars series as fourteen housemates joined the house.
This year the line up is made up of a mix of former Celebrity Big Brother housemates and new celebs taking part for the first time.
All Stars in the house are American couple Speidi, ex Strictly pro James Jordan, model Jasmine Waltz, Austin Armacost, Loose Women regular Coleen Nolan, model Nicola McLean and Calum Best.
Meanwhile, new stars are musician Ray J, model Bianca Gascoigne, actor James Cosmo, X Factor USA finalist Stacy Francis, 90s DJ Brandon Block, footballer Jamie O'Hara and Angie Best.
Tonight (Friday) saw the fifteenth and final housemate confirmed as Jedward joined the All Stars line up.
Calum has already emerged as the front runner to win the latest series of Celebrity Big Brother with bookies Ladbrokes.
Punters reckon Lothario Calum is the one to beat, and he finds himself chalked up as the clear 6/1 favourite for glory.
Ray J, Jamie O'Hara and James Cosmo are close behind at 8/1 apiece, or there's 12/1 on offer that Spiedi's controversial antics are a hit with viewers second time round.
Bianca Gascoigne lands the accolade as the rank outsider of the pack at 25/1.
Jessica Bridge of Ladbrokes said: "Money talks, and punters are backing Calum to come out on top. Unfortunately the same can't be said for his Mum's chances, as Angie is currently friendless in the betting."
Of course it's a VERY long way to go until the final yet...
