At the Library of Congress’s National Book Festival in Washington, D.C. at the weekend, the iconic justice revealed that the singer had reached out to see if she could meet her and introduce her husband-to-be, Alex Rodriguez. Being the total legend that we all know and love, Ginsburg happily obliged, and J-Lo and A-Rod ended up hanging out at her Supreme Court chambers for a chat.

“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,” she told the crowd. “So they came to chambers, and we had a very nice visit. She mostly wanted to ask if I had any secret about a happy marriage. But now A-Rod is traveling with her to concerts all over the world…”

NPR’s Nina Totenburg, who was interviewing Ginsburg at the discussion, then asked her what advice she had shared. Ginsburg, who knows how to spin a compelling story, knew exactly how to deliver.

“On the day I was married, my mother-in-law - I was married in her home - she took me aside and said she wanted to tell me what was the secret of a happy marriage,” she continued.

Then, showcasing her dry sense of humour, she added: “It helps sometimes to be a little deaf”.

Practising selective hearing isn’t just a handy skill for relationships, Ginsburg explained. It’s wisdom that can be used in a variety of contexts - “every workplace, including the good job I have now”.

Ruth Bader Ginsburg shared her marriage advice with J-Lo, and it was truly hilarious
