"Blank Space" hit maker Taylor Swift, 25, and Calvin Harris , 31, were recently spotted a HAIM's concert at The Troubadour in West Hollywood on April 2, Thursday, and their sweetness seems to confirm their rumored romance.

According to E! News, the two wore matching black leather jackets, which are similar to what they wore during a trip to While Foods in Nashville recently. During the concert, Harris was seen wrapping his arms around Swift's waist and at one point, the "Style" singer was seen sitting on his lap.

"When they came out of the club, pushing and shoving ensued as photographers jockeyed for a position outside the venue's private exit," a source told the publication. "Calvin led the way for Taylor and helped her into the car. Calvin was very much the gentleman getting in front of the paps to help her into the car."

Both Harris and Swift are HAIM groupies. Harris worked with the Haim sisters Alana, Danielle and Este on the 2014 song "Pray To God" and Swift usually hangs out with them when they find the time amid their busy schedules.  

Meanwhile, Swift recently dethroned Kendrick Lamar at the number one spot of the Billboard Artist 100 chart dated April 11. With Lamar at number two, Maroon 5 comes at number three followed by Ed Sheeran at number four, Drake at number five, Sam Smith at number six, Ellie Goulding at number seven, Nicki Minaj at number eight, The Weeknd at number nine and Meghan Trainor at number 10.
