Demi Lovato has reportedly split from her boyfriend Guilherme "Bomba" Vasconcelos.

"It wasn't a dramatic split," an insider revealed to People of the couple, noting: "Bomba is a good guy, but the relationship just ran its course."

Vasconcelos, 31, and Lovato, 24, broke up after a few months of dating.

The MMA fighter took to his Instagram account to share a photo with Demi and wrote: "I miss you so much!"

The pair made their first public appearance on New Year's after being linked briefly last summer.
