Their little rookie is here!

Derek and Hannah Jeter welcomed a baby daughter yesterday, The Players' Tribune announced in a tweet this morning.

"Congratulations Derek and @hannahbjeter on the birth of your baby girl, Bella Raine Jeter, born Thursday, Aug. 17,” the tweet read.

The couple, who began dating in 2012 and tied the knot in 2016, hope their kids have as "normal" a life as possible, even though their mom is a supermodel and their dad is a baseball legend.

"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," the Sports Illustrated stunner said in a previous interview.

Their little princess is bound to be both beautiful and athletic!
