Nick Cannon-Amber Rose affair rumours are nothing new. The model has since been linked to her manager since her divorce from rapper Whiz Khalifa. Nick on the other hand has allegedly been carrying on an affair with Amber even while married to Mariah Carey. It's even believed that the latter will cite infidelity as the reason for their divorce. However, the "America's Got Talent" host has since denied the speculations on previous interviews. But his recent lie detector test supposedly proves otherwise.

As reported by the International Business Times, Nick Cannon had a chat with BBC Radio 1Xtra host Charlie Sloth to talk about his personal life. Nick was subjected to a lie detector test while he was asked random questions about his past relationships. Of course, his marriage to Mariah Carey was questioned and the rapper confirmed he and the singer "will be friends for life." Sloth also questioned the 33-year-old about his rumoured affair with Amber Rose.

The video below at the 1:26 time mark shows Nick Cannon being asked if he had "done a 'ting" with the model. According to Inquisitr, Nick was apparently asked if he'd ever had sex with Amber Rose and once again Nick denied the allegations.

"I have not done a 'ting' with Amber Rose. It's the truth, it's the truth," he said.

However, the studio audiences were surprised when Nick Cannon's response triggered a loud buzz from the lie detector test, signifying he had not answered the truth about his rumoured affair with Amber Rose. Sloth could be heard telling Nick "you're lying to me" while the latter laughs out loud and desperately tries to defend his response. Nick could be heard saying "there's no phys...I don't know" but then stops midsentence to blame the machine for his result.

"You know what they say these lie detector tests like when you know it has to be extremely factual that was a hundred percent fact. I don't understand maybe my nerves are bad or something," he said.

Nick Cannon continues to deny the rumours despite the lie detector test result "confirming" his alleged affair with Amber Rose. He told Eonline he doesn't pay attention to the speculations, claiming "the beauty about gossip is there's always another story tomorrow."
