“We’ve all known each other for a long time,” he says. “… But Kim and Jennifer are very, very close, and she’s almost like a mentee of Jennifer, and Jennifer’s mentored her a lot over the years.”

“Now,” he adds “they just go back and forth.

“They mentor each other and they have this really beautiful relationship that goes back over a decade and a half, and it’s nice to do anything with Kim and our family.”

Those family gatherings, Rodriguez says, range from holidays spent together to Taco Tuesdays at the Lopez-Rodriguez residence and even the occasional karaoke night … where, he admits, Kardashian West is a “really good” singer.

Rodriguez’s go-to karaoke show-stoppers? (Aside from his soon-to-be wife Lopez’s hits, of course, which he says he prefers to dance along to.)

“Mine is ‘Don’t Stop Believin’.’ I’m an ’80s-rock kind of nerd — Elton John, ‘I’m Still Standing,’ ‘Piano Man,’” he says. “I’m gonna geek out here.”

In the commercial for the Portal smart video-calling system, Lopez, 50, and Kardashian West, 39, share a call — face masks applied and ready for a “top secret” chat — when Rodriguez enters the room wearing a matching mask of his own and hoping to join in on the BFF time.

“This is such fun,” he says in the ad. “We should do this more often.”
