The 48-year-old singer and actress gave a special shoutout to Rodriguez while performing at the Super Saturday Night pre-Super Bowl show Saturday in Minneapolis, Minn.
"We've been together for one year today. I don't want to get all mushy or anything, but baby, this song's for you. I love you," Lopez said before launching into her song "Us," according to E! News.
Rodriguez attended the concert with his two daughters, 13-year-old Natasha and 9-year-old Ella. He was also joined by professional dancer Derek Hough, with whom he recorded an Instagram video.
Page Six reported Lopez and her children, 9-year-old twins Emme and Max, enjoyed dinner with Rodriguez and his daughters at Manny's Steakhouse prior to the show.
"She wanted to go out," a source said of Lopez. "Jennifer really wanted to be together for their anniversary. They went with all four kids."
"The place was pandemonium," the insider added. "[But] they were seated, tucked behind a half wall by the bar."
