It's "been going on for awhile," a source close to Fernandez-Versini tells PEOPLE. "Both are very similar and happy."
According to The Sun the pair's romance developed in December after the X Factor finale where One Direction gave their final performance before starting their hiatus.
Fernandez-Versini is currently in the midst of a divorce from Jean-Bernard Fernandez-Versini, her husband of 19 months. Payne split up with longtime girlfriend Sophia Smith in October, shortly after revealing they had discussed getting married.
