Cardi B, Offset already married

Hip hop's most high-profile engaged couple have a secret: They're already married.

“Bodak Yellow” rapper Cardi B and Migos star Offset, who celebrated a public engagement in October, actually tied the knot in Fulton County, Ga., in September, according to documents obtained by TMZ.

The marriage certificate is dated Sept. 20, about one month before Offset popped the question during one of Cardi's performances in Philadelphia.
