The couple has yet to release a photo of the little girl, but between her model mom’s killer good looks and her Yankee star dad’s athleticism, we’re sure she’s gonna be a gorgeous baby! Hannah revealed she was expecting a daughter in an essay for The Players’ Tribune  on Feb. 13.

“Pregnant with our first child, Derek and I are looking to the future,” she wrote. “He already has a name in mind — he’s set on it. (We’ll see.) He’ll say when he calls me during the day: ‘So, how are you and so-and-so doing?’ ‘That’s not the name yet, sweetie.’ Whatever her name is, I know she’ll run circles around him.”

Hannah added, “We want our kids’ lives to be as ‘normal’ as possible. They’re going to be born into such an extraordinary situation. They’re going to have to be some strong little people. We don’t want them to be defined by their dad’s name — for them, we want him to just be ‘Dad.’ That will be the piece of him they’ll have that the rest of the world doesn’t. It will be special, and it will be theirs.”

In an interview with Extra, the brunette beauty admitted that she would like a big family. “I want a team. Let’s just get through one and we’ll see how I feel,” she shared. “A couple maybe…three or four.” So we guess this is just the start of a very very attractive family!
