Brooklyn Decker definitely has that pregnancy glow! Andy Roddick's model wife announced she was expecting on May 2 (in the middle of royal baby fever, no less), and the couple looked so in love and glowing in Austin May 4 at the 10th Annual Gala for Roddick's foundation. 

For her date night, Decker, 28, wore a spaghetti strap royal blue dress with blue and white pumps. The Grace and Frankie star was all smiles wearing a crimson statement lip and her hair tied back in a loose, low ponytail. Cementing his hot dad-to-be status, Roddick, 32, wore a navy sport coat with his collar open.

Confirming her happy news on Instagram, Decker — married since 2009 — can't wait to see her husband as a dad. One thing's for sure: He'll no doubt be the coolest dad on the block. "He's just the most clever person I've ever met," Decker gushed to Glamour last year. "He has such a quick mind . . . He's so clever, and his humor is very snarky. It always makes me laugh."

As her body changes with pregnancy, Decker is sure to keep fitness and staying healthy a priority. "Being married to Andy has given me a new appreciation for my body," she told Women's Health in 2012. "He's taught me that it's not how thin you are that matters. It's how your body performs, how it endures wear and tear."

A fan of kayaking, dancing, and yoga, there is one activity Decker won't do: Play tennis with her man! "I ended up hitting all the tennis balls over the fence and smashing my racket because I was so frustrated,” the mom-to-be recalled to Women's Health of the time Roddick tried to give her a lesson. “I told him, 'You don't teach me how to play tennis, and I won't teach you how to model in a bathing suit.' And so far, it's worked."
