WNBA's Glory Johnson -- I'M HAVING TWINS ... With or Without Brittney

WNBA star Glory Johnson just announced ... she's carrying TWINS ... and says it's exactly what she and her estranged wife Brittney Griner planned all along. Johnson says she's 9 weeks preggo with the two kids -- and says, "Its not a surprise for me because this is what we planned for with the IVF Cycle." Her announcement even came with a basketball pun -- "For 15yrs Double-Doubles came with hardwork and dedication...now I've been blessed by God to have "double doubles" for the rest of my life!" Still unclear what role, if any, Griner will have in the children's lives ... since she filed to annul the marriage to Johnson just 28 days after they tied the knot.
