Calvin Harris is breaking out of his post-breakup funk as rumors circulate that he is now dating singer Tinashe after his recent break up with Taylor Swift. Harris and Tinashe have been keeping things low key as a source close to the pair says, "They have been seeing each other on the DL. It's only been a couple of weeks, so it's still pretty casual right now. They've been on a few dates." Calvin met Tinashe in the studio in 2014 when they collaborated on the song 'Dollar signs.' They stayed in touch and now are taking things slow.
