Derek Jeter's Wife's INSANE Bikini Shots ... While Pregnant! (PHOTOS)

Only one question comes to mind when looking at Hannah Davis' new bikini shots ... what took Derek Jeter so long to knock her up?!?!?!

The good folks at Sports Illustrated just released a sneak preview of Hannah's new spread in the 2017 Sports Illustrated Swimsuit Edition ... and they're good.

By the way, the pics were taken just weeks after she learned she was pregnant!!!!

Hall of Famer.
