The baby-faced Ariana Grande may look super-sweet and innocent
, but according to Ed Sheeran, the "Problem" singer definitely has a naughty sense of humor.
"Can I tell you why I was laughing?," he begins to explain. "Basically there were all these big inflatable bouncy black balls bouncing around in the crowd in the finale bit when we go there. And Ariana Grande comes up and stands up next to me, and just looks at me and goes, 'I love big black balls.' In my head I was like, 'If she knows what that means then I love her, and if she doesn't know what that means, it's even better!'"
Ariana, 21, is currently dating rapper Big Sean, 26.
Though perhaps Ariana's dirty joke shouldn't come as too much of a surprise.
"I think people see me as a little cutesy thing," she said. "But I'm literally the most sardonic person you've ever met."
Ariana and Ed joined Taylor Swift as the musical acts performing at this year’s Victoria's Secret Fashion Show -- airing tonight at 10 p.m. EST on CBS -- and though Ed obviously had a good time surrounded by all of the gorgeous models, he did admit that it didn't exactly boost his self-esteem.
"It was fun, but I kind of felt like the hobbit in an elven kingdom," he admitted to Elvis.
