After stepping out in similar outfits in March, the two music stars were seen together at a Kenny Chesney concert where they reportedly showed some PDA. A week later, they were photographed holding hands at a Haim concert in West Hollywood.
While neither Taylor nor Calvin have publicly addressed the rumors, the "Blank Space" singer's good friend Ed Sheeran has given his "seal of approval."
Speaking with IHeartRadio's ZM station, the "Don't" singer shared his impression of Calvin after meeting him last year.
"He's cool. He's a nice guy. A really, really nice guy," Ed said. "There are certain people that are just nice people in the industry. [He's] a good guy. A really good guy."
The Grammy-nominated singer danced around addressing the rumors directly, but it was clear he was supportive of any possible relationship between his friend and the successful DJ.
