Decker, Roddick set to welcome baby

Talk about some good genes!

Brooklyn Decker and Andy Roddick will welcome their first child this fall, the former's rep confirmed to People exclusively.

“I’m happy to confirm Brooklyn and Andy are expecting a new addition to their family in the autumn of this year,” Decker’s rep, Jesse Parker Stowell, says.

The model turned actress, 28, who plays a mom on the upcoming Netflix show Grace and Frankie, announced the news on Instagram.

“So this happened… # the3ofus,” Decker captioned a photo of herself showing off her baby belly.

Decker and retired tennis player Roddick, 32, who were married six years ago at their home in Texas, already have two cute charges in their care: their bulldogs, Billie Jean King and Bob Costas.

Last year, the actress expressed her desire to start a family.

“I love kids. I definitely want kids,” Decker told PEOPLE last April. “I just have to figure out the timing of that.”
