The Cool for the Summer singer, who split with Wilmer Valderrama in June after six years of dating, says a relationship just isn't in the cards at the moment for her, either.
"It's not on my mind, but I welcome anything," Lovato says of her relationship status. "Anything" includes a brief fling with MMA fighter Guilherme Vasconcelos and reportedly a dinner date with New York Giants wide receiver Odell Beckham Jr.. "I'll have fun. But a relationship ... I won't want that for a long time."
While living a life of luxury in the spotlight has its upsides, Lovato lived through dark days. She fought a hard battle of addiction and mental illness in her younger years, and parted ways with Jonas after she had a scuffle with her dancer during the 2010 Jonas Tour, where she was also performing.
"I distanced myself as I was getting involved with self-destructive things," she admits now. And while it was clear Lovato desperately needed to seek help, Jonas was fuming, fearing that the band would be sued.
"I mean, it was bad," he says. "On top of losing a friend, we have seven dates left, it's a big production, people are expecting to see Demi and that's not going to happen."
The pair were eventually able to reconcile, but it took some time for the wounds to heal. "After treatment, I had to have some time sober before I wasn't embarrassed to talk to him. The first time we saw each other since that tour was my [2012 Los Angeles] concert at the Greek [Theater]. We caught up right before the show, then performed. It was an emotional reunion – I got one of my best friends back."
After four years of maintaining her sobriety, Lovato draws on her personal experience to fight for mental health reform in a very active way. "When I went through my s---, I realized it was for a reason – to make a difference," she says. "I can share my story a million times, but it's not as tangible as going to Capitol Hill."
It also helped influence her decision to buck her conservative upbringing and endorse Hillary Clinton for president. "Hillary is in support of mental health care and, yeah, I'm a Democrat."
Though Jonas hasn't revealed who will get his vote, he's very vocal when it comes to protecting LGBTQ and transgender rights. During Jonas and Lovato's July 2 show in Orlando, the performers paid tribute to the victims of the tragic Pulse Nightclub shooting – one of the worst acts of violence against the gay community.
Though his speech was met with accusations of "queer baiting" from some concert-goers, Jonas remains defiant. "I wouldn't change a thing," he says. "That's a moment – and in general the time we're in in this country – where unity, support and raising our hand and saying we can make change is what's important, so it's a shame when people make it about something else."
