Former Yankee Derek Jeter has just welcomed his third child with wife, Hannah Jeter.

The MLB great’s website “The Players’ Tribune” announced the news Saturday afternoon via Twitter, surprising fans who had no idea that the couple was expecting.

“Congratulations Derek and @hannahbjeter on the birth of your baby girl, River Rose Jeter, born Thursday, Dec. 2.,” reads the tweet.

Hannah, 31, was seen just three months ago with their two eldest daughters, Bella, 4, and Story, 2, attending Jeter’s National Baseball Hall of Fame induction ceremony. The Sports Illustrated model did not appear to be pregnant at the event, leading some to believe they’ve welcomed their latest bundle of joy via surrogate.

Jeter dedicated part of his Hall-of-Fame speech to his daughters and wife Hannah, whom the superstar athlete married in 2016.

“To my girls, Hannah, Bella and Story: This day puts an exclamation point on my playing career, which was my first dream,” Jeter said while onstage. “Through you all and with you all, I’m living another one.” 

The former shortstop also took time to address his daughters directly with a message that will surely apply to his newborn, as well.

“Bella and Story: I want you to know that your dad was far from perfect,” Jeter said. “I made my fair share of mistakes on and off the field. But through it all, I tried to do the right thing. I found something I was passionate about and I worked harder than anyone else. I didn’t take any shortcuts to achieve it. 

“I have zero regrets in my career, other than the fact that I didn’t get a chance to share it with you. What I will share is my story. Most of it won’t be what I accomplished on the field. It’s going to be the lessons I learned off of it. I hope I always make you proud.”
