The 42-year-old retired MLB star gushed over Lopez in an Instagram post Wednesday ahead of the 48-year-old singer's pre-Super Bowl LII concert.
"This is for every woman who works till 1 am to get it right, who has the grit to get up when it's not, and who shows the world what it means to give all you have," Rodriguez captioned a photo of himself and Lopez making their way to a Guess event.
"Congratulations on @guess, crush it on @nbcworldofdance and slay it on Super Saturday," he added, referencing Lopez's various projects. "#WomanPower #Inspiring #Empowering."
Lopez serves as a judge on World of Dance, and was named the new face of Guess in November. She and Rodriguez wore coordinating looks to the brand's spring 2018 campaign launch Wednesday in Los Angeles.
"Sometimes I'll say, 'Do you like this or do you like this better?'" the singer told People of choosing outfits with Rodriguez. "He's like, 'Is this a trick question? I like whatever you want to wear!' Yeah, but we help each other out when we can."
Lopez will perform Saturday in Minneapolis, Minn., as part of the Super Saturday Night show. The concert, which will be broadcast live on AT&T Audience Network and DirecTV Now, takes place the night prior to Super Bowl LII.
