London, Oct 22 : Socialite Paris Hilton has revealed that her baby voice and ''''airhead'''' image is nothing but an act.

The hotel heiress made the confession during an interview with British presenter Fearne Cotton who was visiting her Hollywood mansion for a documentary.

''''I would do the baby voice and it''s kind of like this character I made up, but in real life I''m completely different, I''m very down to earth, I''m smart, I know what''s going on,'''' the Telegraph quoted her as saying.

''''It''s kind of like I almost play to the image and kind of have a laugh at myself about it,” she added.

The 28-year-old beauty admits she’s completely different with her friends and during business meetings.

''''I think a lot of people will assume that I''m just like an airhead. But in my everyday life, when I''m hanging out with my friends or if I''m in a business meeting I''ll talk in my normal voice,'''' she said. (ANI)
