Brooklyn and her husband, former tennis player Andy Roddick, are expecting their first child in May. They have yet to announced the gender of their baby.

"We're open to any and all suggestions," Andy told People magazine. "We're going to figure it out as we go."

The Sports Illustrated model originally announced the pregnancy two months ago, posting a beautiful photo of herself in a full-length dress. "So this happened…" she captioned the photo while cradling her tummy. She used the hashtag "#the3ofus."

As is her personality, Brooklyn is using the pregnancy to flex her funny bone a little. After announcing the pregnancy she told People, "Getting congratulated for boning is super exciting. It's strange because you finally admit to your father, 'Dad, I do it.'"
