Okay, you guys, are Joe Jonas and Tayor Swift dating? Or is this just the latest Jonas Brothers rumor? While Taylor Swift says she and Joe Jonas are just friends, he did show up at a recent Swift concert. Hmmm.

Joe Jonas was at Taylor Swift’s Florida concert last weekend, wearing a baseball cap and seemingly trying to keep his identity on the low-down.

Joe Jonas arrived five minutes before Taylor Swift took the stage, and, according to Mishelle Rivera, Assistant Promotions Director for Miami’s Y-100 Radio, “I spotted Joe quickly, but he was trying to hide from the crowds by tucking in-between a few people. He was wearing a baseball cap and real casual dress so he wouldn’t stand out.”

Joe Jonas hung out near the soundboard, next to Swift’s dad.

“He watched only her performance, then walked backstage to the meet and greet area,” says Rivera. “But when he saw people start to recognize him, he hid. It was real obvious he didn’t want people to know he was there to see Taylor.”

So… does this mean Joe Jonas and Taylor Swift are dating?

Taylor Swift told People magazine, “He’s an amazing guy and anybody would be lucky to be dating him.”
