Jennifer previously opened up about her upbringing during a joint appearance with Lynda on BUILD in 2017. When asked whether they used to fight as children, Lynda replied: "Not me and her, but you know there's three of us right? When we were kids those two would beat up on me."

Alex Rodriguez's fiancée responded: "We did not beat up on you. We were all very close in age – don't imagine us on a child infant, it wasn't like that, she's a year and a half younger than me okay!"
