American actress/singer Demi Lovato has been romantically linked to former UFC fighter Luke Rockhold. The former Disney star and the 31-year-old former middleweight champ have been reportedly dating since a few months.

According to a report in celebrity gossip website TMZ, the duo met while she was training at Unbreakable gym in Los Angeles in early 2016.

Lovato's dating reports comes as a shock as she recently broke-up with longtime boyfriend Wilmer Valderrrama. The couple called it quits in June after nearly six years together.

The Heart Attack songstress and the former That 70s Show star had been dating on and off since 2010. Previously, during an interview with HuffPost Live, Lovato opened up about her relationship with Valderrama.

"For us, we wanted to keep our private lives private, and we still do. But as we've been in a relationship on and off, gosh, almost 5 years now... people are seeing us more together. We thought you know what, if paparazzi gets us, whatever," she said. "But, we're in control of what we're able to post online, so we're very open about our relationship."

"I also wanted to give him a lot of credit that he never takes... He'll never take credit for a lot of my sobriety and my recovery but I guarantee it, I wouldn't be alive without him today," Lovato added.
