Nelly was arrested today in St. Louis for ecstasy possession and driving without insurance.
The 49-year-old has long been linked to ecstasy use.
The St. Lunatic secretly wed Ashanti last December, and they are expecting their first child any day now.
We suspect a heavily pregnant Ashanti won't be happy when she hears news of the arrest.
But she's known him forever, so she probably knew what she was getting into.
