The 2012 series housemate sued all of Conor, Channel 5 and programme makers Endemol for libel in the high court.
The claim was over two episodes broadcast in 2012 which saw Conor and Deana clash in the now infamous 'epilator rant'.
In the controversial argument, which saw Conor warned but not ejected by Big Brother, Deana was branded a "f**king piece of s**t."
In her court claim, Deana claimed that Conor's words were defamatory but the judge disagreed.
The judge actually argued that if anyone's reputation had been ruined by the rant it was Conor's.
In the judgement the court said: "The use of the words 'piece of s**t' were vile abuse by McIntyre, but not defamatory.
"McIntyre’s rap may have been ridiculing the claimant [Deana], but the rap was not capable of exposing the claimant to ridicule."
They concluded: "Any reasonable viewer would have understood that the person whose reputation might have been adversely affected by this was the person who made the rap (McIntyre), and not the claimant."
The legal fight however isn't completely over yet as Deana has also launched a separate claim for damages for breach of a duty of care owed by Endemol and Channel 5 to her as a housemate, and for breach of contract against Endemol.
