Cardi B's secret marriage to Offset is exposed! (Proof inside)

Cardi B and Offset took spontaneity to a whole new level -- they got married on a whim ... as in, the day he asked her to marry him. Sources close to the couple tell TMZ ... the Migos rapper woke up one September morning, looked at the "Bodak Yellow" rapper in the eye and straight-up said, "Marry me." She obviously said yes but, believe it or not, that impulse was only the beginning. We're told, that same day Offset and Cardi -- who at this point, we're told was not pregnant -- hired an officiant to come to the house and marry them in their room. The only person besides the officiant to witness the nuptials was Cardi's cousin.
