Kate just announced she's having baby ... posting this pic Saturday from Miami.
She married Houston Astros pitcher Justin Verlander last November. They dated for 5 years. As you know, they got hitched just days after the Astros beat the Los Angeles Dodgers to win the World Series.
Kate captioned the pic, "#PregnantinMiami @justinverlander."
Unclear how far along she is ... but one thing's for sure -- Kate looks great!
