The recently broken couple could be in for a nasty surprise if they both end up entering the villa – and will be forced to live together once again.
There are currently 12 famous faces kicking off the show in South Africa, but – like in any series – they will face tests in the form of bombshells.
And stunning Molly, 30, and Callum, 27, who met on the show in 2020, are amongst those being considered to make a surprise entrance.
A source: “It’ll be a shock for both of them when they come face to face in the villa – they only recently split and it was heartbreaking.
“They were both so sad after the break up – there’s no animosity so it’s on the cards they could fall back in love in the villa.”
Callum famously fell for Molly during the first winter series – dumping Shaugnha Phillips for her after Casa Amor.
They proved everyone wrong and went from strength to strength outside the villa and even moved in together.
But in September of last year The Sun told how the former scaffolder had moved out of their home after taking custody of their pug, Winnie.
Molly got to keep their Pomeranian, Nelly.
A source said at the time that Molly had wanted to get engaged but it hadn’t happened yet.
Just weeks before Callum has spoken about wonderful everything was between them, saying: “We are perfect.
“We’ve got two dogs so we’ve got a proper little family going, it’s lovely.
“We’re just enjoying things that we’ve got at the minute and then family and marriage will eventually come into it.”
