Last week, a jury sitting at Southward Crown Court in London were played a video which showed Tulisa's PA, Gareth Varey, and an undercover reporter discussing Simon's sexuality.
During the footage, the reporter asked Gareth whether Simon "is gay". Gareth replied "Yes", before the journalist asked if he had slept with him.
"No," the court heard Gareth saying, "I know people who have".
Tulisa had stood accused of being concerned in the supply of class A drugs, following a newspaper sting operation in June last year. Yesterday, however, Tulisa's case collapsed after the judge threw it out.
Now that he is able to speak freely about what was heard in court, dad-of-one Simon has released a statement denying he is gay.
Speaking to The Mirror, a spokesperson said: "Simon was referred to during the trial without forewarning, resulting in widespread media coverage of untrue claims regarding his private life.
"In 2014 the question of whether someone is or is not gay is antiquated. (As it happens he isn't, though if he were, he would simply have said so).
"However, the issue was the false suggestion made by Mr Varey that Simon - who is renowned for his honesty and candidness - had thus not been truthful in the public arena and this is what we have been obliged to clarify."
N-Dubz star Tulisa had been accused of offering to help introduce an undercover reporter to an alleged drug dealer. She denied this.
It has been reported that the judge presiding over the case had told the jury that it could not "go any further" because there were "strong grounds to believe" that the undercover reporter at the centre of the trial - a prosecution witness - had "lied" during a pre-trial hearing.
After the case was dismissed, Tulisa released a statement outside court, saying: "Let me be perfectly clear. I have never dealt drugs and never been involved in taking or dealing cocaine.
"This whole case was a horrific and disgusting entrapment by Mazher Mahmood and the Sun on Sunday newspaper."
The case against the alleged drug dealer has also been thrown out.
