While the "Shake It Off" singer's bestie Jaime King is staying loyal to her friend and not dishing on the romance, she definitely seems to approve of the EDM producer.
"He's cool," Sheeran told ZM Online. "He's a really nice guy, yeah. Really, really nice guy."
Swift, 25, and Harris, 31, were spotted about three weeks at a Kenny Chesney concert in Nashville. According to Taste of Country's Twitter account, they were "getting snuggly" during the show.
A fellow concert-goer told E! News, an eyewitness tells E! News, "They were dancing to a lot of songs! 'There Goes My Life,' 'I Go Back,' it was a lot of songs…I didn't see them kissing but his arms were around her. They sure were cute together! They both were dancing, looked like they were having a great time."
The day before, they were seen shopping at a local Whole Foods.
A few days later, the new lovebirds didn't hide their romance at a Haim concert at The Troubador in West Hollywood. They enjoyed the show from private venue, where the pop singer even sat in Harris' lap.
The two have yet to comment on their relationship, but as they left the Haim show, they held hands before taking off in the same car.
