Nicole Scherzinger insists she's "good mates" with Ed Sheeran. The former Pussycat Dolls singer has recently been romantically linked with the 'Thinking Out Loud' hitmaker but has spoken out about the widespread belief they are secretly dating and firmly denied the pair are an item. She said: "It had been going on for so long and Ed and I are good mates, so we decided to just have fun and take the mic." The American beauty first sparked rumours of their closeness when she shared a photo with Ed backstage at his North London concert. Then last month she posted a spoof video on her Instagram account of herself pretending to sing one of Ed's songs, 'Thinking Out Loud', which implied they'd split up. Speaking to The Huffington Post, she explained: "We thought it was quite clever of us. I thought of it all on my own."
