Judge, 46, wrote on her Facebook fan page July 13 that she had something special to talk about with Andy Cohen on the "RHOOC" reunion show, which was taped on July 14: Rodriguez's sonogram.

The most recent season of "RHOOC" featured Judge and her third husband, Eddie Judge, toying with the idea of having a child together, but they decided against it after their experience with a doll named Astro.

Judge's costar Vicki Gunvalson became a grandmother after daughter Briana Wolfsmith gave birth to her first son. Wolfsmith is currently pregnant with another little boy.

Vieth announced the news by Instagramming a picture of his soon-to-be-wife's small baby bump on July 12.
