New mom Mariah Carey had an unexpected visitor in the hospital this week: a social worker, who according to her husband Nick Cannon, was investigating a claim that Carey was abusing her newborn twins by consuming alcohol and drugs while breastfeeding.

Cannon said that the situation might have been triggered after a nurse suggested that Carey drink a small amount of dark beer in an effort to help breastfeeding, and he believes that someone trying to sell the story to tabloids might be behind it.
