Buh-bye Wilmer, hello Guilherme!

Newly single songstress Demi Lovato has apparently moved on with tatted-up MMA pro fighter Guilherme "Bomba" Vasconcelos, reports Us Weekly.

In case you wanted some of the deets on the tough guy: Guilherme is a 30-year-old welterweight fighter from Brazil. (Oh and in case you wanted to know the really important information: He's 6'0" and weighs 170 lbs.)

The source told the mag that Demi and Guilherme met while training at the Unbreakable Performance Center in West Hollywood, but that they aren't serious -- which seems like a good thing to us because the "Give Your Heart A Break" singer just ended her six-year relationship with Wilmer Valderrama and it sounds like she needs to give her own heart a break!

The insider said that Demi is "just having fun," and another insider added, "Demi's still looking to meet new guys." We have no doubt that the sexy star is going to meet a slew of studs while on tour this summer!

It's been quite a summer for Demi. On June 3, the one-time Disney star and the 36-year-old actor announced they had split.

Posting on their respective Instagram accounts, Demi and Wilmer each wrote, "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."

They continued, "Thank you to everyone who has offered us kindness and support over the years. With only love, Wilmer & Demi."

While the world may still be reeling from the long-time couple's break up -- it appears as though both parties are doing well.

While promoting his new partnership with Old Spice's Right Hair Wrongs campaign on July 7, the former "That '70s Show" star, who just landed a series regular role on CBS' "NCIS" starting this fall, told E!, "[I'm] good, very good. It's been a great summer for work, I've done some incredible things."

Meanwhile, Demi, who is currently on her Future Now tour with Nick Jonas through mid-September, spoke with Elvis Duran on Thursday, July 14 about her newly single status, confessing that she feels "free."

In the interview she didn't mention her former flame by name but said, "I stopped giving an 'f' at like 15. You only get one life, so if you don't do what makes you happy in this moment, you're doing yourself an injustice for the rest of your life."

"My life is in the middle of a lot of changes right now," she added. "I don't really a have a house at this moment, so I'm actually kind of living out of a suitcase on the road, so my tour bus is my home right now."
