lohan...please....she would win. Paris probably had her maid cat fight some other girls maid growing up....actually not a bad idea for a story....swedish vs spanish....sorry...I digress........
Linsey had a more "normal" upbringing and I'm sure has been in a real fight and even with the 4 inch size diff she's heavier then Paris and besides Hilton's reach advantage it would be wrestling almost immediately.
Just my .02
