Demi Lovato [1] and Charlie Hunnam [2] were spotted having lunch together in LA on Wednesday. The two stars, along with Brazilian jiu jitsu champion Rigan Machado, sat for a meal and were photographed leaving the restaurant separately. An unlikely pairing? Perhaps. But back in April, Demi and Charlie appeared side by side [3] on an episode of The Late Late Show With James Corden and discovered their mutual love of jiu jitsu — maybe they were discussing techniques? Demi did receive her blue belt in August [4]. Or perhaps there's a chance that Charlie could pop up as a love interest in one of Demi's next videos [5]? Whatever the nature of their conversation, we kind of love that these two are hanging out.
