Rob Gronkowski is one of the all-time great football players in the NFL. He has won two Super Bowl rings and has become one of the most famous players on the New England Patriots.
So imagine the surprise of 27-year-old fan Lauren Meizo, who's stuck in the hospital waiting for a heart transplant, when "Gronk" walked through the door to visit her.
Lauren had posted a video online explaining that she would love to meet Gronk and, somehow, that message got back to him.
He showed up with an autographed football, a teddy bear and a jersey.
Lauren has been through a lot and said she feels mentally strong enough to deal with whatever comes her way. But, she also said she appreciated the boost in energy Gronk delivered by walking through her door.
