Just kidding you silly geese, that's not her sister Haylie, that's an elephant! Hilary Duff attended the "Night with the Raj" Polo Ball at International Polo Club in Palm Beach, Florida last night. Reportedly one of the elephants tried to get a little "frisky" with her (who wouldn't when she looks this good?). So is the elephant an upgrade or downgrade from her sister? More pics after the jump!
