Andy Roddick is going to be a dad! 

The 32-year-old retired tennis champ and his wife, Brooklyn Decker, are having a baby. 

Model-turned-actress Decker, 27, posted this photo announcing the news to her Twitter account on Saturday: 

The couple married in Austin, Texas, in 2009. 

A news outlet made a small gaffe when they accidentally posted Decker was expecting with current tennis pro Andy Murray, who recently got married himself, spurring this exchange:

Congratulations to all parties involved.
