When Jennifer Lopez needs marriage advice [1], who does she turn to? None other than Supreme Court Justice Ruth Bader Ginsburg. At the Library of Congress National Book Festival in Washington DC on Aug. 31, Ruth recalled J Lo reaching out about a month ago to hear some words of wisdom [2] ahead of her forthcoming wedding to Alex Rodriguez [3].

"I was called up about a month or so ago by Jennifer Lopez, and she said she would like to meet me and introduce her fiancé Alex Rodriguez," the 86-year-old judge [4] told the crowd at a discussion panel. The three eventually got together, and Jennifer asked if Ruth had "any secret about a happy marriage." And being the smart woman she is [5], Ruth offered up great counseling that was inspired by the advice her mother-in-law once gave her. "On the day I was married, my mother-in-law — I was married at her home — she took me aside and said she wanted to tell me what was the secret of a happy marriage," Ruth continued. "And I said, 'I'd be glad to hear it. What is it?' And she responded, 'It helps, sometimes, to be a little deaf.'"

During an appearance on The Tonight Show Starring Jimmy Fallon in September, J Lo recalled Ruth's advice [8], saying, "It was so simple and wise." As simple as the advice might seem, it apparently helped. In 1954, Ruth married lawyer Martin D. Ginsburg [9], and they stayed together until Martin's death in 2010. Meanwhile, Jennifer walked down the aisle three times [10] and was married to waiter Ojani Noa from 1997 to 1998, dancer Cris Judd from 2001 to 2002, and singer Marc Anthony — with whom she shares 11-year-old twins Max and Emme [11] — from 2004 to 2014.

This time around, J Lo feels she's found the one. After her engagement to Alex [12], the "Medicine" singer [13] opened up to People about their relationship and how much their love has grown [14]. "We're really happy [15]," she told the publication in March. "Everything that we do, we do together. He knows my dreams [16] and I know his dreams, and together we feel like we're stronger . . . we're constantly supporting each other [17] in our individual endeavors and thinking about all the things that we can build together."
