"You dated one of the Jonas Brothers, right? Which one did you date?" Chelsea Handler asked the 21-year-old singer. "Joe -- the middle one," Lovato replied.
"Which one's the cute one?" Handler went on to ask. The "Made in the USA" songstress paused for a second, but was quick on her feet. "They have a new niece, and she's really, really cute," she quipped. "She's like a week- and-a-half old." (Kevin Jonas and his wife Danielle welcomed their first child, daughter Alena Rose, earlier this month.)
Lovato has stayed friends with ex Joe, 24, since their split in 2010, but also revealed that the relationship wasn't all that serious to begin with. "We dated for like a month. Everyone made it seem like it was this big, big deal."
Handler then explained that fans probably thought it was a big deal because they were young stars who were ahem, "popping" each other. Completely taken aback by the insinuated sex talk, Lovato giggled: "There was no popping."
Lovato is currently performing on her Neon Lights tour, and has kept it in the Jonas family by asking Joe's brother, Nick, 21, to be her creative director while on the road.
