Alex Rodriguez is truly grateful for all Jennifer Lopez has brought to his life.

“Jennifer has given so much to me and my kids over the last two years,” the former baseball star tells PEOPLE in this week’s cover story.

“Her best quality is undoubtedly her generosity. I see it every day and my kids see it as well.”

One of the greatest gifts from their union for A-Rod was watching his daughters, Natasha, 14, and Ella, 10, grow so close to Lopez’s 10-year-old twins, Emme and Max.

“Our kids have become best friends and that keeps us both grounded and appreciative,” says Rodriguez. “We couldn’t have asked for anything better than the four of them getting along as they do.”
