What does Taylor Swift call Calvin Harris in private?

We all know him by his stage name Calvin Harris, but we hear Taylor Swift actually calls the muso something VERY different!

According to Us Weekly, the 25-year-old Blank Space singer uses the 31-year-old's real name behind closed doors.

"Taylor always calls Calvin by his birth name, Adam, and never Calvin in private," a source reveals.

Calvin was born Adam Wiles, but adopted the showbiz name Calvin Harris, because he thought it sounded more "racially ambiguous."

"My first single was more of a soul track, and I thought Calvin Harris sounded a bit more racially ambiguous," the DJ revealed in an interview with Digital Spy back in 2009. "I thought people might not know if I was black or not. After that, I stuck with it."

We wonder what Calvin's high-profile exes, Rita Ora and model Aarika Wolf, called the British star when they were dating him - and whether it's changed since they split up?!
