Calvin Harris, Nicole Scherzinger party together

London: Scottish DJ Calvin Harris was spotted partying with his close friend and former The Pussycat Dolls singer Nicole Scherzinger at a club here. Harris, who recently split from singer Taylor Swift, and Scherzinger were photographed partying and smiling happily with friends on the dance floor at Tape London, reports  "Nicole was out for the evening with her girlfriends. Calvin being there was a coincidence," a source said.  In an Instagram photograph shared by Zues Sherlock, Co-Founder and Partner of Tape London, Harris and Scherzinger are seen in high spirits.  The shot was captioned: "Old school selfie vibes with my crew last night." They were later photographed leaving the club together in the wee hours of the morning, with Harris reportedly giving Scherzinger -- who is currently dating Bulgarian professional tennis player Grigor Dimitrov -- a lift home.
