Mariah Carey was visited by Child Protective Services shortly after giving birth to her twins.

The singer and husband Nick Cannon - who became parents to son Moroccan Scott and daughter Monroe on April 30 - were shocked when she was accused of putting the babies at risk by drinking alcohol and taking drugs in her hospital room, with the 'America's Got Talent' host branding the allegations "ridiculous".

He told TV talk show host Piers Morgan: "Recently, the Child Protective Services were called with allegations that there was some drinking and drugs and all that going on, wild in the hospital, which makes no sense to me - how would a hospital allow that?

"It all started when a nurse suggested to my wife that if you drink Guinness, the dark beer, the yeast improves breastfeeding. 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.

"I spoke to the person from the Child Protective Services, I was like, 'This is ridiculous. We're going to make sure that this isn't a case.'

"To even have to deal with that, my wife in the state that she's in, we're in the hospital, to even have to think about someone possibly wanting to investigate your children. it's sad at the end of the day."

Nick, 30, also admitted he is astonished at the lengths people have gone to with their attempts to get pictures of the babies.

He added: "There's been photographers actually in the hospital posing as different people or people trying to get pictures of the kids, which is really sad when you think about people trying to make a buck off newborn babies."
