"It's really crazy," Lovato, 17, told me at the Nickelodeon Kids' Choice Awards. "I definitely did not expect this at all. But, you know, I'm going through it with my best friend so it's pretty awesome. I think it was just time to be open and not hide anything."
Yes, the 20-year-old JoBro isn't just her boyfriend, he's also her best friend.
So what is Lovato loving most about her beau (besides their awesome nickname, Jemi)? Read on to find out…
"Honestly, it's all about how comfortable we are with each other," she said. "He's seen me with sweatpants on and with no makeup. I've seen him at his worst and his best. It's great. Like I said, we're best friends."
Will Jemi be making more music together? "Yeah, maybe," Lovato said. "You never know. I mean, it seems like we're always doing duets together. But I don't know where my music is going to go…Right now, I'm just focusing on Sonny With a Chance."
Jonas and Lovato's Camp Rock: The Final Jam costar Matthew "Mdot" Finley has high hopes for the latest Disney duo. "I think they're going to last," he said at the Last Song premiere. "They're a great couple. They understand each other."
FYI: Lovato will be The Soup on Friday.
