Reality telly regular Calum previously entered the CBB house only last year but could be back inside in January.
After finishing third in CBB in 2015, Calum went on to join the cast of E! reality show Famously Single.
Now sources say that Big Brother producers want him back to provide some 'eye candy' for the rumoured all stars series.
A source spilled: "Channel 5 are keen to make sure next year’s series is the sexiest yet so Calum was an easy choice.
"They already have a host of good looking girls lined-up and they think Calum would be perfect for them."
"He was a big hit with the girls last time," they added.
Calum is one of numerous celebs rumoured to return for next January's Celebrity Big Brother.
Alongside the model, other past housemates who could be back include Angelique 'Frenchy' Morgan, ex Strictly pro James Jordan, BB7's Nikki Grahame, BB1's Nasty Nick, American couple Speidi - Spencer Pratt and Heidi Montag - and model Jasmine Lennard.
The upcoming series of Celebrity Big Brother is expected to launch in the first weekend of January with some sort of 'All stars' twist.
Channel 5 haven't confirmed anything at the moment but it's widely expected we'll get back some familiar faces from past series in one form or another.
There have been claims we might get a full ‘all stars’ series, perhaps with a ‘villains v heroes’ theme.
However other rumours say the Celebrity Big Brother 2017 cast could be a mix of ‘old stars and new stars’, with both returning housemates and first time celebrities entering the house.
