UFC and Bellator MMA fighter who dated Demi Lovato dead at 38

Ultimate Fighting Championship (UFC) veteran Guilherme Vasconcelos, who also competed for Bellator MMA, passed away on Tuesday at the age of 38. “Bomba” cut his teeth on Season 3 of The Ultimate Fighter (TUF): “Brazil” and made headlines outside the cage for his brief romance with singer Demi Lovato.

“Of all the students I had, you were the bravest,” longtime jiu-jitsu coach, Cristiano Lazzarini, wrote on social media (translated by MMA Fighting). “Fearless, unbeatable. In moments of chaos, a machine. In trivial moments, a sweet boy. We had a machine that had a bit of everything.”

Vasconcelos was 0-1 in UFC and 3-3 for Bellator MMA.

“Your MMA debut, with a win against a man that had won 10 in a row and had 19 fights, was of the happiest moments of my life in the sport,” Lazzarini continued. “Unbreakable. So many trips together, so many battles. From blue to black belt, from first to last MMA fights. Man, how much I love you. Unbelievable. Rest in peace, brother.”

A cause of death has not been revealed.
