Taylor Swift and Calvin Harris Show PDA at Kenny Chesney Concert

Don't expect those Calvin Harris and Taylor Swift dating rumors to die down any time soon.

After the 25-year-old "Style" singer was spotted out with the 31-year-old DJ/music producer in Nashville on Wednesday -- curiously dressed almost exactly alike -- the two attended a Kenny Chesney concert together on Thursday, where they were spotted showing some PDA.

Nashville concertgoers snapped pictures of the rumored couple at the concert, one showing Calvin wrapping his arms around Taylor from behind. The two were also video-taped holding hands.

Taylor was at the concert to join Chesney onstage to sing his hit "Big Star," while Calvin reportedly cheered them on. Dressed in a long-sleeved crop top that showed off her slim stomach and a matching high-waist skirt -- while the Emporio Armani underwear model kept himself covered in a black jacket -- the two made quite the attractive pair.

Calvin -- responsible for such huge hits as Rihanna's "We Found Love" and Ellie Goulding's "I Need Your Love" -- is no stranger to dating pop stars. He dated Rita Ora for a year before their reportedly messy split last June. Meanwhile, Taylor's last serious relationship was with One Direction's Harry Styles, and we all know how that panned out.
