The 23-year-old "See You Again" singer stopped by The Ellen DeGeneres Show, where she asked about the time he swapped spit with the "All About That Bass" pop star on live TV at the American Music Awards.
"Meghan is my best friend," Puth deferred. At which point DeGeneres pointed out the placement on his hands on Trainor's butt and he joked, "That's where you put hands when you're friends."
"I always wanted to make a record like Marvin Gaye's records, where you would put them on this magical record player and everybody would want to, ya know, get down with each other," he said. "Not like that, you dirty-minded people!"
"And we teased it in the video too, where it cuts off," he continued. "It's all a visual aesthetic for what the song is."
The now three-time Grammy nominee, who will drop his debut album, Nine Track Mind, on Jan. 29, also recalled getting discovered by DeGeneres.
"I actually -- I’m very sorry about this -- I hung up on you guys," Puth revealed. "I mean, I’m a sophomore in college...It's very unrealistic for The Ellen Show to call you."
