Taylor Swift and Calvin Harris seen hand-in-hand outside Hollywood club, fuelling rumours they're dating

Taylor Swift and Calvin Harris have fuelled rumours they are dating after they were seen leaving a concert hand-in-hand.

The country singer turned pop megastar was spotted holding hands with the 31-year-old DJ and producer outside The Troubador in Hollywood on Thursday night.

Pictures showed the 25-year-old Shake It Off singer, wearing a lacy black top and skinny trousers, being led from the venue by Calvin.

They were rushed into a waiting blacked-out 4x4 after spending an evening together there watching a performance by Haim, an all-girl pop rock band from Los Angeles.

According to US website TMZ, Taylor was sitting on Calvin's lap during the gig.

The sighting appears to support rumours the pair have been romantically linked since the BRIT Awards last month.

The pair were also reportedly spotting holding hands at another show - a concert by Kenny Chesney in Nashville, Tennessee last week.

Calvin has been single since splitting from his model girlfriend Aarika Wolk last month.

Past love interests of Swift include actor Jake Gyllenhaal, John Mayer and One Direction star Harry Styles.
