Andy Roddick and Brooklyn Decker served up some happy news on Saturday. The couple will welcome their first child this fall.

Decker announced her pregnancy news via Instagram accompanied by a photo of the model holding her stomach. "So this happened... #the3ofus," she wrote.

Her rep also confirmed the news with E! News: "I'm happy to confirm Brooklyn and Andy are expecting a new addition to their family in the autumn of this year."

No one was happier for the couple than Chrissy Teigen, who simply tweeted, "!!!!!!!!!!!!"

The 28-year-old Decker and 32-year-old Roddick married in 2009. The tennis pro retired in 2012, making his announcement during the U.S. Open.

Decker spoke about having kids last year, but realized a baby would mean less alone time with her hubby.

"I love kids. I definitely want kids. I just have to figure out the timing of that," she told People in April 2014.

She already got some practice playing a mom-to-be in the upcoming Netflix series, "Grace and Frankie," starring Lily Tomlin and Jane Fonda. The full first season premieres on Friday, May 8.
