Ex-Hollyoaks actress Stephanie, 23, has faced accusations she's been faking her pregnancy due to a lack of photos of her midriff or a scan.
But she put those claims to bed this week, posing for the front cover of a magazine showing her blossoming bump in all its glory – and insisting again that Jeremy is the father.
He's previously cast doubt on that claim.
Now, he's responded via Twitter, saying: "Everything will be dealt with accordingly and mature, but a baby doesn't fix a toxic relationship, end of discussion."
Jez also replied to an article containing quotes he gave Ireland's TVNow in June in which he said: "I'm not going to be a dad. If she is pregnant, it's not mine. If I was a dad, I'd be 100% no, 110%, the best dad in the world. But you'll see in the future that it's not my kid, and she'll look like a mug."
He said: "Article I done months ago, time will tell, I don't need to reiterate again. We were broke up for weeks."
Stephanie and Jeremy met on CBB in January, which was controversial because she was in a relationship with model Sam Reece at the time.
Once the show ended, they began a relationship but it was rather rocky, with several public splits and reunions until a final split in May this year. Then, Stephanie announced her pregnancy.
Jeremy, however, refuted her claims he was the father, claiming she'd told him she'd had her period since they split last.
Since then, he's remained silent, while Stephanie has kept fans updated on the progress of her pregnancy, tweeting about cravings, morning sickness and baby clothes shopping.
However, she has faced accusations of faking her pregnancy, with one person tweeting her: "You're not even pregnant. We're all just waiting for the inevitable 'miscarriage horror' story. You're a mess."
Steph replied: "Absolutely disgusting! This is why I'm not sharing any photo [sic] as there's so many vile people! I've been under enough stress."
But now she HAS shared the first baby bump photos, she has a message for critics: "To all them trolls,haters and nasty people who have not let me enjoy my pregnancy,u can see my bump &my scan when u buy a copy! Up yours (sic)."
