All new parents have their hands full, but Mariah Carey and husband Nick Cannon also dealt with a very unexpected visitor in the hospital where their daughter and son, Monroe and Moroccan, were born April 30.

“Child Protective Services actually came to me,” Cannon told Piers Morgan on CNN Thursday, “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.”

But it’s hardly as scandalous as it sounds: Cannon believes someone involved in Carey’s care was overheard discussing a beer that allegedly boosts breastmilk production. Many moms of twins receive lactation tips specific to the challenges of feeding two newborns, but most can probably count on more privacy than Mariah Carey.

“It all started when a nurse suggested to my wife that if you drink Guinness, the dark beer, the yeast improves breastfeeding,” Cannon added. “I don’t know if someone heard that [and] were saying my wife was drinking beer. People will do anything to try to conjure up a story.”

Cannon’s theory is that a mundane conversation became a wild rumor only because of the new mom’s celebrity. According to Us, he said the rep responding to information about alcohol in the patients’ room understood the circumstances and agreed the allegation was ridiculous.

“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 children,” Cannon said. “It’s sad at the end of the day…when you think about people trying to make a buck off newborn babies.”

Guinness beer tips aside, nursing twins is serious business for some moms, as ‘Modern Family’ star Julie Bowen proudly explained during a chat with George Lopez last year. On the other hand, twin mom Jennifer Lopez caused a mini-scandal in the parenting blogosphere when she confidently told People magazine she was forgoing breastfeeding altogether.
