The Wanted challenged One Direction to a fight at Madison Square Garden last December, but One Direction bailed at the last minute.
The Wanted's Max George said: "The fact is, we asked to meet them at Madison Square Garden and they did a runner. That's the 100 percent God's honest truth. They got the car pulled up to the back of the stage and got straight in it. Zayn Malik was being a "d."
Member Jay McGuiness said: "I think until we speak to them personally, we won't really know what the real situation is."
No comment from the One Direction boys.
