Taylor Swift and Calvin Harris make it official at Haim concert

LOS ANGELES, April 3 (UPI) -- Taylor Swift and Calvin Harris fueled rumors about their relationship Thursday night by showing up hand in hand to the Haim concert in West Hollywood.

Clad in matching black jeans and leather jackets the pair was photographed entering and exiting The Troubadour nightclub together.

The alleged couple first sparked speculation about their alleged romance last week, after they were spotted grocery shopping together in Nashville and were later seen holding hands at a Kenny Chesney concert.

Swift, who has previously dated the likes of Harry Styles, Jake Gyllenhaal and John Mayer, told Rolling Stone last September that she hadn't dated anyone in almost two years.
