Ed Sheeran is traveling the country with Taylor Swift on her “Red” tour, and is requested to perform at some of the biggest award shows in the U.S. But while speaking with “The Ralphie Show,” he revealed that he no longer approaches artists whom he is a fan of.

“I’ve been really disappointed a bunch of times,” Sheeran told me during an interview taped the weekend of the Billboard Music Awards. “A lot of people are d–ks.”

“Country artists are wicked,” Sheeran said, using the term as a form of endearment. “I’m English, and I’m a massive hip-hop fan. I grew up listening to a lot of rappers. When I was at The GRAMMYs and I met some people, it was just a bit like… you know, I’m not asking for anything, just a handshake. Some people wouldn’t even shake my hand.”

The “A-Team” singer revealed later that the particular encounter he was referring to involved rapper Nas. Sheeran owns all of the star’s albums.

“It’s not that hard to be nice man, for 15 minutes,” Sheeran continued. “One of the nicest people I ever met was Paul McCartney, and he doesn’t have to be nice to anyone, because he’s Paul McCartney.”

Sheeran did have a great encounter last weekend at 95.5 PLJ’s Summer Blast-Off, where he and Gavin DeGraw ended up jamming on stage together and exchanging pleasantries over Twitter. Another massively successful artist who is great with people: Sheeran’s tour-mate.

“Most big artists do pay-for meet-and-greets,” Sheeran noted, explaining how Swift’s “Club Red” works. “She sets up a club, they put pizzas in it, there’s like a photo booth in it, there’s Coca-Cola, all of this cool stuff, and her team goes out in to the crowd every night and picks out the most dedicated fans.”

The songwriter says most of the time, the fans that weren’t able to afford the best seats in the house end up with an once-in-a-lifetime opportunity of hanging out in Club Red with T-Swift.

“For her to do something like that every single night, to walk off stage and not even take a break… and go in to Club Red, and do an hour and a half meet-and-greet for 20 people is pretty cool,” Sheeran said. “Because it’s not just a picture and a ‘See ya later,’ it’s (more).”

Another one of Sheeran’s friends that doesn’t mind giving back is Harry Styles. The last time Ed and I spoke, he revealed the story of Styles buying Domino’s Pizzas for the homeless in Los Angeles. When I informed the singer that The Mirror UK and subsequently the world picked up the story, he smiled.

“You know what, I’m down with Papa John’s as well,” Sheeran responded. “Can we just put out a story about them? They do these cheese-sticks that are out of this world. We don’t get them in England.”
