Joe Jonas told fans to "get out of here" when they asked to take a picture with him.
The Jonas Brothers musician and his girlfriend Blanda Eggenschwiler were standing outside Sauce restaurant in New York on Saturday (19 January) when he was reportedly unhappy to be approached by fans and refused to take a photograph with them.
College student Andy Hertfeld told Radar Online: "After we approached him, he shook his head no.
"It was late, which we understood, but my friend asked for a picture anyway. That's when Joe flipped out on us he said, 'We do so much for you. We do everything and you want a picture? Get out of here.' My friend was in tears."
Hertfeld claimed Joe's brother Nick also ignored them and Joe's friend even mocked Hertfeld and his pals.
He alleged: "Nick didn't even stop or look in our direction. The entire thing completely broke my heart."
"One of his friends, a tall girl with short brown hair, started making fun of us.
"She was going on and on about my friend saying, 'Is he going to cry now?' and Joe just laughed right in our faces.
"I was always one to stand up for him towards haters, but now I'm starting to see what they mean by his attitude since he's been surrounding himself with certain people.
"I've done everything I can to 'support' the Jonas Brothers, then we get treated that way? He should be a little more grateful."
