This evening Celebrity Big Brother kicks off its brand new series with a new batch of celebrities in tow. While some famous faces - Calum being one of them - have been heavily rumoured, their identity will be kept a secret until tonight's launch when they enter the house.
But has Vas already spilled the beans?!
Taking to Twitter earlier today, Vas pretty much confirmed Calum is one of this year's CBB contestants.
He tweeted: "Excited to see my pal @CalumBest on tonight's #CBB launch ..."
Oops. We bet show bosses won't be too happy!
Earlier today, reports suggested Calum would be joined in the house by Ex On The Beach star Chloe Goodman, in hope of a CBB romance.
According to the Daily Star, the show is hoping sparks will fly between the pair, as Calum admitted he fancied the reality star after previously meeting her.
A source told the paper: "By [putting] them both in the house, the producers are trying to guarantee a bonk."
Other rumoured housemates include Katie Hopkins, Patsy Kensit, US blogger Perez Hilton and Kirk Norcross' ex-fiancée Cami Li.
This year the house has taken on a Twisted Fairytale theme and host Emma Willis has said she has "such high hopes" for the upcoming series.
Eek. And the countdown begins...
Celebrity Big Brother kicks off tonight on Channel 5.
