Mariah Carey is said to be "terrified" that her twins may have the autoimmune disease her husband Nick Cannon was diagnosed with.
Radio and TV presenter Nick has suffered a bout of health issues in recent months, and after being treated for blood clots in his lungs, was eventually told he has a Lupus-like disease.
Now, sources say that Nick's wife Mariah fears that their eleven-month-old twins Moroccan and Monroe may have the same illness.
"[Mariah is] terrified that one or both of the twins will be stricken with the disease," an insider told the National Enquirer.
"Mariah’s world would shatter if anything happened to her babies."
Earlier this week, Nick revealed that he and Mariah are flying the twins out to Paris to celebrate their first birthday later this month.
