Louis Tomlinson is ''incredibly messy''.

The One Direction singer has admitted his tour bus habits often annoy his bandmates, Liam Payne, Harry Styles and Niall Horan, and he thinks he has inherited his untidiness from his mother.

He said: ''I don't mind saying I am incredibly messy. It doesn't bug me, but it annoys the other boys sometimes.

''I think I get it off my mother - she's a bit messy too. She probably wouldn't like me saying that.''

The 'Little Things' hitmaker loves playing jokes on his bandmates, even if it means disrupting one of their gigs.

He explained: ''Every now and then during a concert I'll change a few songs words to something random and stupid, just to throw the boys off.''

And off stage, Liam most frequently falls victim to Louis' jokes.

He added to Top of the Pops magazine: ''I think Liam [is the victim most often]. I don't know why. He's not gullible or anything. I just think it's cos me and him banter with each other a lot and he gets the brunt of it.''
