47-year-old Darren has a string of celebrity exes thanks to his previous relationships, but we almost didn't recall him and Wedding Crashers' star Isla being all loved-up. Until last night, that is.
Chatting with Danniella Westbrook and John Partridge, Darren brought up Isla in conversation, admitting her found it pretty awkward bumping into her again, especially as she was with her now husband Sacha Baron Cohen when they crossed paths...
Darren, John and Danniella had volunteered to be confined to the box in order to unlock the kitchen and bedroom for their fellow housemates. The trio took to telling stories to pass the time and, recalling a wedding he went to in the past where a slew of his former flames were also in attendance, Darren said he didn't find it awkward at all - only with Isla, as he is such a big fan of Sacha.
He told his housemates: "I went to a wedding... and it was like that moment in Four Weddings and a Funeral when you sit down and then all of a sudden there were like four or five of my exes there with their now partners."
"It was all alright," he admitted. "But the only awkward one was Isla - who I hadn't seen for a long time. So you've got that moment of bumping into an ex which is always an awkward one, but she was with Sacha Baron Cohen who I'm a massive fan of."
Darren continued: "I was meeting the ex's new husband, but I wanted to say, 'I think you're brilliant, mate!' I hope I did it enough that he knew I was a fan because I think he is a genius."
Isla and Darren dated back in 1998 for two years, before later splitting in 2000.
The pair met while both starring in the stage production of Summer Holiday and at the time, it has been reported, that Darren said Isla was the "first girl he's been in love with."
He and Isla later became engaged, but broke up not long after blaming their 'hectic lifestyles' for putting strain on their relationship.
While Isla is now happily married to Sacha and shares three children with him, Darren has been married to his wife Stephanie Dooley for ten years. The pair have a daughter together, Madison, and Darren is also dad to son, Corey, who he shares with ex Suzanne Shaw.
Fans of CBB saw Darren enter the Celebrity Big Brother house on Tuesday night, where he joins fifteen other celebrities including Gemma Collins, David Gest, Geordie Shore's Scotty T, Kim Kardashian's BFF Jonathan Cheban and US star Tiffany Pollard.
