Demi Lovato's sorta-ex, Wilmer Valderrama, is running his mouth about their on-again-off-again relationship. Interestingly though, like Lovato, Valderrama isn't confirming nor denying that there was actually a relationship to begin with.

Interviewer Perez Hilton grilled Valderrama about his exploits with the 'Give Your Heart a Break' singer. "What does a 19-year-old have to do dating a 31-year-old? What is a 31-year-old doing dating a 19-year-old?" Hilton asked.

"It wasn't even like that," Valderrama said. "It was just a real interesting time for her. We were really just best friends." (Really? Best friends who have sleepovers and make out?) Valderrama continued, "And to be honest, I couldn't be more proud of her ... She's amazing, she's a great human being. And I'm so proud of her considering all of the different obstacles and everything she's been through. I mean, she's got a pretty good head [on her shoulders]."

Okay then, so what's this business about Valderrama being bffs with Lovato's other ex, Joe Jonas?

"He's a really cool guy. He's my bro," Valderrama said. "There's absolutely nothing weird about embracing someone who has some history that's intertwined with yours. I think if you're very secure with who you are, there is no reason why people shouldn't embrace the moment, and we shared a moment." Fair enough, but can't this guy get friends his own age? Still seems skeevy to us.

We're happy Lovato's seemingly moved on. She was recently spotted getting cozy with the much less creepy, much more age-appropriate Logan Henderson of Big Time Rush. Go girl!
