"Jen, it doesn't take a trophy, medal or plaque to identify a true champion," Rodriguez said next to a photo of Lopez walking the red carpet.
"To millions of young women who have watched you and have been inspired and empowered to do amazing things in their lives, you are a champion," the former baseball star continued.
"For countless musicians, dancers, actresses, and performers who have seen and emulate your passion, drive and worth ethic to find their own success, you are a champion. To your children, your family, your coaches, your staff and your extended family, you are a champion," he said.
"To everyone whose lives you enrich daily you are a champion. And don't you ever forget it," Rodriguez concluded.
Rodriguez and Lopez got engaged in March after two years of dating.
