Los Angeles - Calvin Harris is reportedly dating Tinashe.
The Summer hitmaker is reportedly "casually" seeing the Superlove singer behind closed doors.
A source said: "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 - who split from Taylor Swift last month - met Tinashe in the studio in 2014 when they collaborated on the song Dollar Signs and were also rumoured to both be writing for Rihanna at the time.
The source told the New York Post newspaper's Page Six column: "They stayed in touch and recently started hanging out again."
The couple were seen on a date at Nobu in Malibu on Saturday and their affection for one another was clear to see.
An onlooker said: "It was clearly a date. They were super close."
