Last month it was revealed that Stephanie had split from her Hollyoaks co-star Owen after nine months of dating.
The news came after Stephanie denied their relationship was 'on the rocks'.
Speculation that all wasn't well began to surface a few weeks before when it was claimed that 20-year-old Owen had moved out of her home and blocked the actress on Instagram.
A source told The Sun: "Stephanie and Owen have decided to split after weeks of trying to work through their differences. They decided to end it and Steph is insisting there's no going back.
"She couldn't be more devastated as she saw a real future with Owen, particularly as he's been a father figure to Caben."
The source added: "Steph is absolutely heartbroken and devastated it's over – she wanted to be with Owen forever and now all of a sudden she's mourning the loss of him in her and Caben's lives."
