Rumours are making the rounds that Demi Lovato is reportedly dating MMA fighter Guilherme "Bomba" Vasconcelos.
The link-up rumours came in the wake of Lovato's claims that she felt 'free' after her split with boyfriend of six years Wilmer Valderrama.
According to sources, the 'Stone Cold' hit-maker and the professional athlete Vasconcelos "are not serious" about their relationship.
The Mirror, quoted a source, as saying, 23-year-old Lovato was "just having a fun" with Vasconcelos.
Another source added, "Demi's still looking to meet new guys."
Lovato had earlier admitted that she was excited about her future after her split.
The 'Heart Attack' hit-maker and Valderrama called off their relationship last month nearly six years of together.
