Louis Tomlinson suffers from partial deafness as a result of the piercing screams at One Direction concerts.

According to The Mirror, the 20 year old has been left partially deaf in one ear because of the high-pitched screaming of the band’s fans.

One Direction has recently returned from a tour of America, Canada and the UK.

Tomlinson said: "I am going slightly deaf in my right ear. It's tinnitus... something like that."

The star claims that he suffered from a headache for three days after the band’s Liverpool concert.

"All our fans are always very loud, especially Scousers."

It is thought that the young heartthrob is suffering from tinnitus, which can lead to deafness if not treated properly.

A source close to the band said: "Screams during gigs have started affecting the boys on stage.

"They are only young and still developing, so management insist they wear hi-tech earpieces and filters to reduce the volume of the screaming and the music.

"When Louis made his comments he had really bad earache. Thankfully, this has now cleared up but he knows to be careful in future.

"When watching them, even the band's security team and family have to wear earplugs, too."
