The singer and the UFC fighter have been spending a lot of time together recently.
Demi Lovato and her new man UFC fighter Luke Rockhold have made their relationship Instagram official, by posting their first couple’s pic together.
Demi and Luke have been rumoured to be dating for a few weeks now, but after spending Saturday night together at UFC 205 the pair were ready to go public with their romance.
Luke posted the black and white photo of the pair first, which showed them sitting together at the event in Madison Square Garden.
Demi then followed by sharing the same image on Sunday evening and writing, ‘About last night…’.
Last week a source told E! News that the pair had been spending more time together, after meeting while Demi was training at the Unbreakable Performance Center in Los Angeles.
"Demi is hanging out with Luke. It's pretty new and fun at this point. She likes being around him," the source said.
"She just got out of a serious relationship [with Wilmer Valderrama] so she is not looking for something that serious but if something evolves naturally over time she is willing to go with it and explore it.”
"She thinks Luke is a cool dude and he makes her smile,” the source added. “She is the kind of girl that takes day by day and just lives in the moment."
Demi was previously in a six year relationship with actor Wilmer Valderrama. In June the couple, who were thought to be getting married, shocked fans when they announced their break-up.
