According to Us Weekly, the singer has rebounded from her very long-time boyfriend, Wilmer Valderrama, by getting into an intense new relationship with Guilherme Vasconcelos. An MMA fighter, Guilherme Vasconcelos goes by the nickname “Bomba.”
Both stars train at West Hollywood’s Unbreakable Performance Center. Having ended a six-year romance with Valderrama in June, the 23-year old singer isn’t looking for anything serious at the moment. She “just having fun,” says an insider, adding: “Demi’s still looking to meet new guys.”

Last month, Lovato and Wilderrama stunned the celebrity gossip universe when they announced their split. But they at least did so very amicably, via a joint statement that reads:

“After almost six loving and wonderful years together, we have decided to end our relationship…This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as friends. We will always be supportive of one another.”
