Harry Styles finds it ''pretty easy'' to work out if a girl is only with him because he's famous.

The 21-year-old One Direction star - who has dated the likes of Taylor Swift and Kendall Jenner - insists he knows if a girl likes him for who he is as a person.

When asked if he worries girls only want him because of his fame, he said: ''I think people who would approach someone in that way for the wrong reasons are usually quite transparent. I think it's pretty easy to tell what someone's intentions are.''

However, bandmate Niall Horan insists most of the stories about girls they are romantically linked to are just rumours and admits he tries to ignore it as it can ''wreck your head''.

Speaking on Britain's breakfast show 'Lorraine', he said: ''You have to kind of get over it, if you keep reading all those stories it's just going to wreck your head but like you know whatever, you can have friends, we're all allowed to have friends.''
