The housemates fell for each other in the just-finished series of CBB, which courted controversy as Stephanie entered the house with a boyfriend, model Sam Reece, whom she'd been dating for a year.
Now, she's split with Sam and is "working on a relationship" with Jeremy.
Darren was asked about the couple during his appearance on ITV's Loose Women today. "Only time will tell," said Darren. "In that house, once you get out into reality, I don't know. He certainly told me his feelings were real."
He added: "Romance and love come up in all different places in life and there is no reason why it can't work coming from a reality show. And I wish them all the best, of course."
Stephanie was among those watching today's show, as she tweeted: "Proud of my dad @DarrenDOfficial he's so amazing! @loosewomen so proud and buzzing for him."
Meanwhile, Jeremy, 25, appeared on The Ray D'Arcy Show over the weekend, where he admitted he felt bad for how things had worked out with Sam, but he couldn't hide his feelings toward Stephanie, 22.
"We're working towards a relationship. We are both still single," he said. "Like I said, she's come out of a relationship in the house, basically, so there's no point jumping straight into it. Take two weeks, take a breather, see your friends and family. You need breathing space after that."
