With her wealthy background, extensive wardrobe and party-going lifestyle, Paris Hilton is sometimes perceived as a bimbo.
But the 27-year insists she is just misunderstood.
In an interview with Heat magazine, the heiress says: ‘I think a lot of people have seen me on The Simple Life and think I'm a "spolit airhead". But I was playing a character.
'The producers said they wanted Nicole and I just to be crazy and funny and say outlandish things.
She added: 'I'm a lot more serious and shy...and if I'm not out, having to be, you know, "on", I'm at home just chilling and wearing sweat pants.'
In the magazine, Paris appears in a photo shoot wearing a white dress and a huge platinum blonde wig which extends to the floor.
Paris, who split up with boyfriend Benji Madden last year, says she doesn't make it easy for men trying to get her attention.
She reveals: 'I'm always really hard to get with guys. There's a process they have to go through.
'I'm very old fashioned really and I'll make them have, like, a million dates before the get a kiss.
'People are surprised because they think I've been through so many men, but it's not true. I don't really talk to guys - apart from Benji, who I was with in the past year.
'I'm not ready to move into another relationship. I think it'll be good for me to be alone and find out who I am.
'One day I'll find someone, but for now I don't want to be with anyone.'
The heiress, who's latest reality series Paris Hilton's British Best Friend stars on ITV2 on January 29m, also revealed that she is a budding artist.
'I have a room in my house where I paint. I've been offered an exhibition, which I might do next year,' she says.
