Paris Hilton denies reports that she has fake big ol’ titties.
Paris’s rep states that her chest may appear to be enhanced due to recent photos that surfaced showing her with some bigum’s but he states that she is wearing:

A prototype from her Paris Hilton ‘push-up’ bra line. Paris has never had plastic surgery.

Its not like it’d be easy for her to get plastic surgery and not have anyone spot it; I mean who hasn’t seen her naked?
