During a task to be aired on tonight's show, the Irish model opens up to housemates when they are all asked about regrets they may have about their time in the house.
Jez says: "I have no regrets in life. We're in a bubble in here…I regret getting a bit too involved (with Stephanie)."
Viewers have watched Jeremy and Stephanie grow closer and closer over the past two weeks and even share a kiss, despite Stephanie having a boyfriend in the outside world.
While Jeremy has said he needs to step back from Stephanie, it hasn't actually happened...
And just after making the confession about regrets, he tells the former Hollyoaks star that he's actually fallen in love with her! "I just embrace being with you. You fall in love and have a connection with people, it's good to take it home and makes you stronger, it's something we're not going to do ever again," he says.
"We're on Celebrity Big Brother. We'll look back at his and we fell in love on TV. Regardless what anyone says, that's what happened with me. Another chapter of my life. When I look at you I want to look at you more."
She replies: "Stop! You're gonna make me cry."
Stephanie's boyfriend Sam Reece has been tight-lipped about what's happening with Jeremy. He hasn't tweeted or spoken about Stephanie since 11 January, when he said he was withdrawing his support from her in the house but they still remained a couple.
Many fans have been desperate for Big Brother bosses to put Sam in the house so he can confront Stephanie and Jeremy on camera about their flirtations.
