No "Stone Cold" hearts for Demi Lovato!

The pop star is reportedly dating MMA fighter Guilherme "Bomba" Vasconcelos, who seems to have really fallen for the Confident singer.

The two have been hanging out for months, but Vasconcelos sparked romance rumors when he shared a photo of the pair celebrating New Year's Eve on December 31.

In another Instagram post, he shared a photo of the two holding one another while out for a walk, captioning it with a heart emoji.

Lovato and Vasconcelos, who both train at the same gym in Los Angeles, were first spotted getting close on the fighter's social media back in July, according to Entertainment Tonight.

Their potential new relationship comes just weeks after the performer broke up with UFC fighter Luke Rockhold, who were last seen together attending an event in November, and months after she split from her boyfriend of six years, actor Wilmer Valderrama, in June.
