Is it possible to look more natural after plastic surgery? "High School Musical" star Ashley Tisdale, 22, just got a nose job -- and her newly shaped schnozz made its first appearance yesterday at Madison Square Garden.

Tisdale claims she got the plastic surgery to fix a deviated septum -- the same excuse reason expressed by Jennifer Aniston and Cameron Diaz for their rhinoplasty. Something smells fishy!

Ashley still looks great -- Eskimo kisses for everyone!
