While Adele, Lady Gaga, and Mariah Carey‘s tune-belting appearances might be the stuff of Carpool Karaoke dreams, diva Jennifer Lopez‘s epic car-ride jam session will forever a special place in our hearts as “The One Featuring Leonardo DiCaprio.”

The Titanic heartthrob inadvertently made a brief, albeit memorabgile, cameo during J.Lo’s big appearance on Carpool Karaoke last March, the Latina songstress reminisced during an episode of The Late Late Show on Thursday.

Catching up with host James Corden, who admitted that he hadn’t seen the World of Dance judge since their musical ride around Los Angeles last year, the pair remembered texting the Revenant actor out of the blue. (For a refresher, Corden penned this hilarious message: “Hey, baby, I’m kind of feeling like I need to cut loose. Any suggestions? Let me know. J.Lo.”).

And while the British funnyman and the superstar spent the rest of their karaoke session getting down to hits like “Booty” and “Jenny from the Block,” the highlight of the segment was when DiCaprio texted back with the most epic response.

“His reply was, ‘You mean tonight boo boo, club-wise?'” Corden remembered, laughing, as Lopez recalled being overwhelmed with embarrassment while waiting for a text back for 20 minutes.

“He answered back like it was totally normal that I would speak that way to him. It was awkward,” she said. “I guess he calls every girl ‘boo boo.’ I don’t know!”

For those who want more of the booty-shakin’ hitmaker, Lopez will be back on the show for the second Late Late Show Carpool Karaoke Primetime Special 2017 on May 22nd. While “Bon Appetit” star Katy Perry will be making her debut spot in the passenger’s seat, the “Ain’t Your Mama” singer will be channeling Gwyneth Paltrow and testing out her dance prowess with a Toddlerography dance lesson.
