Frankie Cocozza and Kirk Norcross have reportedly fallen out.
The pair met on Celebrity Big Brother and remained friends after the show, even planning to move in together and become the "Hugh Hefners of Essex".
They were also close to securing their own TV show, as Channel 5 was interested in commissioning the UK's answer to The Girls of the Playboy Mansion.
However, their friendship is said to have cooled after Norcross became jealous of the X Factor star's success with women and popularity in the media.
"They're both blaming their busy work schedules for them growing apart," a source told the Daily Star.
"But Kirk has been getting jealous of Frankie's success with the girls and his TV projects.
"They tend to go for the same girls and lately it's been ending in an argument. Kirk has taken himself off to Dubai for some time out from it all."
Cocozza was recently rejected by model-turned-bodybuilder Jodie Marsh.
