ONE Direction member Zayn Malik and The Wanted’s Max George have exchanged a series on insults through Twitter.
Although both boybands have denied rumours of a feud, open Twitter warfare broke out on the site last night.
The feud began when Malik called Max George a "geek" after he posted a photo of himself at a party with Usher.
"Does that mean I'm 'in'? George responded, to which Malik replied: "I'm not sure why your still talking to me mate conversation ended when I called you a geek.
"Your display [picture] just how's how much of a wannabe you are."
George's bandmate Tom Parker got involved, tweeting “I think “1 stripes” got his knickers in a twist bro”
Malik responded: "Mate, if I had a face like yours my hair would be the last thing I'd worry about.
"Let's not even start discussing vocal ability boys. Would love to chat gotta run though rehearsals."
George responded: "Enjoy rehearsals. Stay off the bud... It clearly makes u cranky," before Malik said: "Alright chlamydia boy ;)."
One Direction member Louis Tomlinson then told Parker to "pipe down bad boy", Parker responded by calling the One Direction member a "sass master".
George later tweeted: "Tell me you're problems without the 8 security in NYC... The only problem I have with you is the s**t banter. Grow up son."
"I'd f**king love to, see you in new York big man ha u clown," Malik hit back.
