Stewart, 22, is once again going through a rough patch in her relationship with Robert Pattinson after he moved out of their love nest. It is said that he caught the actress' messages to director Rupert Sanders, with whom she had a fling in July last year.
Stewart was spotted being driven to Swift's pad by a female friend and she looked relaxed on her way, reports a website.
Swift herself had been through a tough time when she broke up with singer Harry Styles in January this year, after a much-hyped relation of few months. She was later linked to her close friend Ed Sheeran.
