Nick Cannon's affair with model Amber Rose is reportedly to blame for his divorce from wife Mariah Carey. The rapper has since addressed this rumour in previous interviews. However, Nick once again denied speculations by taking the lie detector test and denying the affair.

Nick Cannon took the lie detector test while on a guest appearance at the BBC Radio 1Xtra studios to chat with popular host, Charlie Sloth. According to UK's Mail Online, the 33-year-old was initially asked about his previous relationship with Kim Kardashian. However, the topic veered off toward his rumoured affair with Amber Rose, and once again Nick denied the speculations.

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

While Amber Rose is supposedly to blame for his divorce from Mariah Carey, Nick Cannon, on the other hand, is allegedly the reason for Amber's divorce from husband Whiz Khalifa. According to Mail Online, the pair has been romantically linked following the model's divorce.

The International Business Times adds that Mariah Carey will cite infidelity during the divorce proceedings. Nick has reportedly been unfaithful during their marriage, which points to his affair with Amber. The latter is even rumoured to be carrying Nick's child. Amber Rose was photographed looking rather heavy and sporting what appears to be a baby bump. However, these reports have neither been confirmed nor denied by Mariah's or Amber's rep.

Likewise, Nick claims dating is not on his list right now. Talking to People, he admitted his kids are his number one priority following his divorce. "Obviously the dating thing will come down the line, but right now I'm just slowing down," he said.

While the Nick Cannon-Amber Rose affair speculations continue, Mariah Carey, on the other hand, has remained mum. According to IBTimes, she has been busy performing before vast audiences as she tours the world for her "Elusive Chanteuse" concert. Nick, on the other hand, told Charlie Sloth during the lie detector test that he and the diva "will be friends for life." He also denied rumours that he and Mariah are friends with benefits.
