Though slated to appear on "Live With Kelly And Michael" yesterday, Nas spent most of the day in the emergency room being treated for vertigo. Nas apologized for missing the appearance, and promised to reschedule for a new date.

Vertigo is not a pleasant feeling, and it's no surprise Nas couldn't tough it up for the interview. The vertigo began on a recent plane flight and has persisted since, but Nas is expected to make a full recovery.
