While the housemates haven't even entered the compound yet, it seems show bosses are expecting sparks to fly when Calum and Chloe are introduced.
And it won't be for the first time!
According to Daily Star, the pair met at a celebrity party last year and Calum admitted to fancying model Chloe, although she had a boyfriend at the time so nothing happened.
(Although Calum shouldn't feel too bad… just recently Chloe admitted that she'd turned down a date with Idris Elba as well because she wanted to focus on lavishing her attention on her new puppy!)
Could this be second time lucky for Calum?!
A source told the paper: "By betting them both in the house, the producers are trying to guarantee a bonk."
Oooh… will they be the next Chantelle & Preston? Chanelle & Ziggy? Lee & Casey & Jasmine?!
CBB opens its doors for a brand new series tonight when a slew of famous faces will be locked up together once again for our entertainment.
Other names rumoured to be entering the house include controversial TV personality Katie Hopkins, X Factor's Marcus Collins, gossip blogger Perez Hilton, model Alicia Douvall and actress Patsy Kensit.
Former TOWIE star Kirk Norcross' ex-fiancee Cami Li is also thought to making an appearance.
The show's host Emma Willis recently said: "I have such high hopes for the series – that's how good I think it's going to be. You won't not recognise [any housemate] if it stays like this. This year seems like a proper stellar cast and that's always great to watch."
This year's CBB theme is Twisted Fairytale which we imagine can only mean plenty of drama and some mean twists thrown in.
Meanwhile, former housemate-turned-spinoff show host Rylan Clark recently told Reveal that housemates should never try to be something they are not.
"Be yourself. There's no f****** hiding in that house, there's cameras everywhere! And, don't walk out of there and blame the edit!" he said.
"We can only edit what you say or do, so what you say or do decides what we can show. If you say a throwaway comment and get picked up on it, well you said it, we didn't put the words into your mouth! Be prepared because everything you say and everything you do WILL be shown. Do not think it won't be!"
Catch all the action from tonight on Channel 5!
