One down, more to go. It seems that Calvin Harris has already won over one of Taylor Swift's BFF's.

Last week, a New Zealand radio station couldn't help but ask Ed Sheeran about the rumored relationship between Taylor and Calvin, and Ed was game to support the budding romance.

"Yeah, I'd give the seal of approval," Ed said said. "I met him probably like a year ago ... [he's a ] good guy. Really, really good guy."

Taylor and Calvin fanned romance rumors after they were spotted holding hands at a Kenny Chesney concert in Nashville in late March. A few weeks prior, Taylor and a few gal pals headed to Las Vegas to see Calvin perform at Hakkasan, too. Last weekend, all eyes were again on Sin City to see if Taylor would be on hand to watch the EDM artist perform, but Calvin came down with food poisoning, forcing him to cancel.

Neither Taylor nor Calvin commented on their relationship. Ed, for that matter, didn't exactly confirm the relationship either but he seems to be all in on Calvin.

"He's cool. He's really a nice guy," Ed said. "A really, really nice guy."

The only question is whether Taylor is officially calling Calvin "Mine" just yet.
