'Thinking Out Loud' singer Ed and former Pussycat Doll Nicole are said to have grown close in recent months, enjoying low-key nights out to pubs.
However, a rep for Ed has denied that their relationship is romantic.
According to The Sun, Nicole reached out to the 24-year-old after telling him that his songs helped her to get over her split from Formula One driver Lewis Hamilton.
A friend of Ed's told the newspaper: "As far as he's concerned they were in the early stages of dating and he's been open about it with close friends and colleagues. It may not develop beyond those dates but they're definitely tight."
Meanwhile, a friend of Nicole's added: "They're extremely close. Nicole says he is the male version of her."
Nicole split from Lewis in February. She was linked to Swiss footballer Pajtim Kasami in June after they were pictured kissing on the Greek island of Mykonos where she was celebrating her 37th birthday.
Meanwhile, Ed split from girlfriend Athina Andrelos in March. In July he was linked to blonde model Louise Johnston, but he denied any romance, saying his love life is "non-existent at the moment".
