It only recently came to light that Sammy would spend three years behind bars after he pleaded guilty to scamming two pensioners out of £34,000.
Now it's come to light that the Love Island 2018 star has allegedly ended her relationship with a source revealing that Dani is heartbroken.
"She is absolutely floored by what's happened with Sammy. She knows she has to make massive changes in her life and she's so distraught...
"All she knows is that her baby boy Santiago is the only thing that matters now and she is trying to work out how best to look after him as a single parent.
"She needs time to think it through. Sammy completely downplayed the court case every step of the way," the source told the Daily Mail.
They added, "He led her to believe he hadn't done anything too serious and that he would get a suspended sentence now she knows the full horror of the crime...
"She is broken. She feels desperately sorry for the two men he scammed and whose lives he ruined."
