The Wanted: "Our US Tour Has Been Unbelievable"

The 'Warzone' singers also say they can't believe how quickly their US fan base has grown.

The Wanted have described the experience of touring America as "unbelievable' and admitted they never expected to be so well received stateside.

The 'Lightning' singers are halfway through their ten-date jaunt across the US and say it has been an amazing time for them.

"Unbelievable, like we never expected it," Max George told MTV News this week.

"The States is one territory in the world we always wanted to crack, and that's like the ultimate," Max explained. "It's been amazing."

"It's all been really quick actually, and we've only been over here for a week and we've seen it grow massively in just a week," band member Tom Parker added. "That's the power of the internet. Social networking crosses over into so many different territories that for us it's been crucial."

The band performed in Philadelphia earlier this week and admit they were "speechless" after several of their tour dates sold out.

The Wanted's US tour continues tonight (26th January) with a performance in Chicago, Illinois.
