Mariah Carey and Nick Cannon got some unlikely visitors after welcoming twins Moroccan and Monroe on April 30.

"Child Protective Services actually came to me while I was in the hallway and said that they were here to see me because there had been allegations that there was drug and alcohol use during the stay in the hospital," Cannon, 30, told CNN's Piers Morgan on Thursday.

"I was like, 'Well, how would that even be possible? How could the hospital even allow that?'"

Fortunately for the first-time parents, Child Protective Services' visit was all a big misunderstanding.

"It all started when a nurse suggested to my wife that if you drink Guinness, the dark beer, the yeast improves breastfeeding," Cannon explained. "I don't know if someone heard that, but then they were saying my wife was drinking beer. People will do anything to try to conjure up a story."

"When I spoke to the person from Child Protection Services, they said, 'This is ridiculous, we're going to make sure this isn't the case,'" Cannon recalled. "To even have to deal with that, with my wife in the state that she's in while we're in the hospital, to even have to think about someone possibly wanting to investigate your's sad at the end of the day."

After all, Cannon concluded, "it's really sad when you think about people trying to make a buck off newborn babies."
