Earlier, Steph appeared to share a private conversation between herself and club dancer Caroline Pope, who previously denied sleeping with Jeremy behind Steph's back. Jeremy had also strenuously denied these claims.
Appearing to confirm they had split after declaring "sorry for hoping on true love. I'll never love anyone again", Steph took to Twitter again later in the night and hit out at "fame hungry girls" in more now-deleted tweets, which were screen-grabbed by Reveal.
She tweeted: "Everyone has been against me and Jeremy. Done everything they can to split us up. Yet I still stood by his side and tried to overcome the odds. Stupid girls rumours and cheering lies. No one has ANY idea what this has done to me. [sic]
"All your press just to sell a story for money. What happened to love and letting people to happy together? For me when I've only been abused. To finally thinking I had someone to love...[sic]."
She later slammed "fame hungry girls hoping to make a few pound", adding: "It's disgusting. But well done."
These tweets added further speculation that her romance with Jeremy had come to an end.
A spokesman for Stephanie was unavailable for comment when contacted by Reveal, while a rep for Jeremy had no comment.
Yesterday, Jeremy had once again denied the cheating allegations that he bedded Caroline in Newcastle - rumours which first surfaced after he had been evicted from the Celebrity Big Brother house.
Jeremy was forced to address them again after a new interview by his CBB pal Scotty T claimed he had been unfaithful on that night.
Slamming the claims, Jeremy tweeted yesterday: "So sick to death of hungry begs selling stories for a few quid to try ruin ppl relationships. I love steph and would never hurt her end of."
However, soon after, Scott too claimed this wasn't the case, tweeting that his quotes had been "fabricated" in a newspaper interview where he was quoted as saying: "I see them doing this whole love thing, but then I hear he's off shagging girls. I mean he shagged one of my mates, she's called Caroline Pope."
Taking to Twitter, Scott declared: "Just for the record that's not what was said..that has been fabricated to the max, I have no reason to drop people innit!! #betterthingstodo. I did not say that Jeremy cheated, he wasn't in a relationship at that point any way! But it's not true ano for a fact he loved her #jefanie."
Steph and Jeremy found love in the CBB house but their romance was controversial because she was in a relationship with model Sam Reece at the time.
Once the show ended, Steph ended things with Sam for good and she and Jeremy became official.
However, they had a brief split last month - which lasted all of 24 hours - and which also led to them cancelling their first joint TV interview on Loose Women.
Once back together again, their interview was rescheduled for the following week where they explained that their brief split was just a big "misunderstanding".
