The relationship between the 'I'm a Celebrity...Get Me Out of Here!' stars "fizzled out" towards the end of December, reported Daily Mirror.
21-year-old Ex-Miss Universe contestant, Willerton and Joey, 23, become close during the jungle show and shortly after leaving the show announced in December that they are dating.
"Joey's now hot property and she will be gutted not to cash in on his success," a source said.
"ITV hoped they would stay together and star in their own show, but now it won't happen. Things fizzled out towards the end of December," the source added.
