There have been many rumored causes of the Mariah Carey-Nick Cannon split, but throughout it all, reps for both parties have denied there was any infidelity involved.
That may be the case, but a new report suggests that Mariah certainly suspected Nick of sleeping around.
It's already been rumored that Mariah hired a security team to prevent Nick from flirting with other women, and now it seems her suspicions and insecurities only got worse as her marriage began to fall apart.
“She would send her assistants to spy on him during tapings of America’s Got Talent in New York City,” a source close to the couple tells Radar Online.
The insider adds that the spying continued even after the couple had separated, and Carey frequently harassed Cannon by phone:
“She would send her assistants to spy on him during tapings of America’s Got Talent in New York City...It was just sad to see because Nick used to brag about how amazing his wife was to everyone on set."
Cannon was apparently one of the last to realize that Mariah's suspicions had gotten out of control.
Sources say Cannon's family begged him to leave Carey for years before he finally decided that they should live separately for the sake of their children.
