Reports of a new romance between the pair surfaced last month (Feb15) when they both attended the BRIT Awards in London, and speculation about Swift's new man increased this week (beg23Mar15) when they were pictured shopping together in Nashville, Tennessee.

The pair attended a Kenny Chesney concert, where Swift was a special guest, in the city on Thursday night (26Mar15) and footage published on shows them walking through the Bridgestone Arena auditorium holding hands.

Pictures on the site also show Scottish DJ Harris wrapping his arm around Swift's waist as they watch the show.

Harris split from pop star Rita Ora last year (14) while Swift has previously been linked to Harry Styles, John Mayer and Jake Gyllenhaal.
