The "All About That Bass" singer is quick to add that it never went any further than a kiss with Puth. "And then we never did it again. Ever," she says. "When we'd hang out, it would be like buddies."
Last October, Trainor admitted to ET that her career can oftentimes hurt her in the love department.
"Even without the fame, if I walk into a room -- I kind of have that personality where I just take over the room," she said. "I'm like, 'Hey! M-Train's here! What's up!' Which is very intimidating for guys alone, and then on top of [that] being a pop star -- I get it. I don't think they're less interested, I think they're just intimidated."
She added, "It's fine, I'll wait for him. [I'm looking for] someone who's a gentleman, someone who opens that door. A dude pulled out a chair for me the other day and I was like, 'Whoa! OK, nice!' That's new for me. I liked it. And if they're funny, that's awesome."
