The 23-year-old 'Love Story' hitmaker has been linked to her fellow singer but both have denied the rumours, reported Sun online.
Taylor has recently hired the interior designers to redecorate her 11 million pounds house after buying it in March.
She has known to have promised Sheeran that she will decorate a boys' room so that he will have somewhere to stay when he comes to visit.
"Taylor and Ed are really good pals and their friendship has grown even stronger since they started the tour. They were on the road together when the deal went through on her house and she's been sharing all of her ideas for decorating with him," a source said.
