Plastic or real: star makeovers

Scarlett Johansson: With just a slight refinement to her formerly-bulbous nose, Scarlett looks amazing.
Lady Gaga: People still love to make fun of Lady Gaga's "Poker Face," but she looks much better after having a nose job! We're glad that the surgeon didn't go overboard; she still looks like herself, not someone else entirely.
Jennifer Aniston does not deny that she has had not one, but two nose jobs to "correct a deviated septum," (yeah right!) but some people think her plastic surgery addiction goes beyond just slimming down her naturally-wide nose. There are claims that Jen also indulges in face lifts, Botox, and other facial fillers. Some people also think Jen underwent a breast augmentation in 2010, but we're not sure if this is evidence of a boob job or just good old-fashioned Photoshop.
Kate Beckinsale: Kate was always beautiful, but her nose job, tooth veneers, and possible gum-reduction (not to mention a good eye brow waxing!) refined her look and made her even more stunning.
Michael Douglas considering what he has been through these past few years (he battled cancer, his wife was hospitalized for bipolar disorder, his son went to jail, etc.) we think he looks pretty great! His most recent subtle face lift did not iron out all of his charismatic wrinkles, giving him a more natural look befitting an aging Hollywood icon.
Timothy Olyphant: Hunky actor Timothy Olyphant got himself a new set of veneers, and we think they make his smile even better looking than before! We're also wondering if there's some Botox at work on his line-free forehead and around his eyes.
Ashlee Simpson: In one of the most well-known examples of good plastic surgery, Ashlee Simpson swapped her large Roman nose with a more slim, straight version in 2006. Though she denied having work done at first, her nose job was so obvious that it really changed her entire appearance! While she was always pretty, her new nose suits her face much better.
Tara Reid: Yes, yes... we are as shocked as you are to find Tara Reid on a list of BEST plastic surgeries! Considering the horrible state of Tara's stomach and breasts, it is nice to see that she found a good plastic surgeon for her recent facial work. The fine lines around Tara's eyes have been completely erased, and the tip of her nose has been slimmed as well.
