It's been said that the CBB house is set to welcome a slew of famous-faced past housemates for its twentieth series for a Gold Stars vs New Stars special.
That would mean fans will see new celebrities enter the house, alongside previous CBB housemates, and rumour has it Calum Best will be one of the celebs making a return.
Calum appeared on Celebrity Big Brother during its fifteenth series, alongside Cami Li, Perez Hilton, Katie Hopkins and eventual winner Katie Price.
He finished in third place on the show.
According to Daily Star, Calum could be back for a second stint on CBB. A source told the publication: "Calum is confirmed to go back on the show next year. 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," they added. "And they think Calum would be perfect for them."
When Calum had appeared on CBB before, he was dating ex-girlfriend Ianthe Rose Cochrane-Stack, but they went on to split in July 2015.
He had then been linked to Brandi Glanville, who appeared alongside him on E! show Famously Single, but speaking to Reveal back in March, Calum revealed he was single.
And speaking of future romances, the 35-year-old told us: "I would very much want to find somebody. I would happily find somebody to share stuff with, but I'm not pushing it."
Adding what he looks for in a girl, Calum said: "I like good manners - they're essential. They've got to be witty and sarcastic. That's why I love the UK so much because the people I meet here and who I've dated in the past, there's a really dry humour. There's a super sarcastic'ness to it here, that I love.
"I want somebody who can hang out in the couch in their sweats, but can then go for fancy dinners. An all rounder. A good person, it's as simple as that."
If Calum does head into the CBB house, reports suggest he'll be joining former Strictly star James Jordan, The Hills stars Spencer Pratt and Heidi Montag, model Jasmine Lennard and last series' winner Stephen Bear.
Channel 5 are yet to confirm any details surrounding CBB's new series.
