Best and worst of 2011, did they or didn't they? And who's body parts are requested most.

Body wraps, Botoxed brows, butt lifts, plumped up heels, and fat-melting procedures… just a few of the secrets celebs have to keep the glossy mags and HD from ruining their flawless facades.

Dr. Anthony Youn, a top celebrity plastic surgeon and former star of E!'s Dr. 90210, gives SHAPE the scoop on who may or may not have gone under the knife, who did and shouldn't have, and which celebrity body parts his patients are asking for.

SHAPE: Let's start with the best and the worst of 2011. Who's had the best plastic surgery results in your opinion?

Dr. Youn: Kris Jenner underwent a facelift on [her E! show] Keeping up with the Kardashians. Her jawline is tight, her skin is smooth, and she looks completely natural! Kris is an example of great celebrity plastic surgery.

As for the worst, Suzanne Somers had a Stem Cell Facelift. Suzanne is what we plastic surgeons call a ‘pillow face.' Her cheeks are plumped up and her lips look like two hot dogs. Some plastic surgeons believe that stem cells injected into the face can give a long-lasting plumpness to the face. For her sake, let's hope these plastic surgeons are wrong.

SHAPE: There are so many celebrities who appear to have had something done but it's hard to say for sure. We always want to know ‘did they or didn't they?' Give us the scoop.

DY: Jersey Shore star Jenni Farley aka JWoww is denying reports of having work done on her face, but in my opinion she's undergone some non-surgical treatments, like injections of Restylane to fill in her wrinkles and Botox to smooth her forehead. It's one way the star may be trying to fight off premature aging caused by living an unhealthy lifestyle.

Ali Lohan is another young star who is said to be ‘laughing off' reports that she underwent plastic surgery earlier this year, but like her sister Lindsay, I believe she has definitely toyed around with lip injections.

SHAPE: Which star body parts are patients requesting?

DY: Plastic surgeons received an increased number of ‘butt lifts' being requested after Pippa Middleton came into the spotlight.

Scarlett Johansson's lips have overtaken Angelina Jolie's as the most coveted in Hollywood. They are full, luscious, and match her soft face well. They also appear to be totally natural. How can I tell? Photos of Scarlett in her early teens reveal the same full lips.

Natalie Portman's cheekbones are the best in the biz. Even after losing weight for Black Swan, her cheekbones remained high, youthful, and attractive. They are the most striking part of a very beautiful face.

After having her rhinoplasty in 2006, Ashlee Simpson's nose became the most requested one in plastic surgery. Ashlee's nose transformed her into a glamorous, gorgeous Hollywood starlet. Noses aren't meant to look good, just blend into the rest of the features of her face. Ashlee's nose job did just that.

SHAPE: What are some popular procedures celebrities are doing in general?

DY: We all know about Botox, but celebrities are also using their own stem cells and blood to create a younger, healthier glow, while at the same time eliminating the risk of side effects and reactions. Another way stars create their flawless skin is a treatment called the Tri-Laser Facial. This laser treatment clears up three common problems at the same time: sun spots, wrinkles, and fine lines.

For those who wonder how the stars are able to prance up and down the red carpet in the most exotic high heels, it's because they get Restylane filler injections in the balls of their feet before a big event. This creates a cushion effect and lasts up to six months.

With all the stress and intensity that comes along with being a Hollywood star, it's amazing that the stars don't sweat. It isn't better genes. The real reason is that they get Botox injections in their underarms beforehand. This physically prevents the sweat glands from operating.

Almost every star, whether they admit it or not, has used a body wrap before hitting the red carpet, a movie set, or sometimes even the grocery store. Body wraps are the easiest, fastest way for short-term weight loss-you can lose up to 10 inches in a single hour. But it's temporary. Another new procedure is called Zeltiq, which actually freezes the fat away.

Of course, there are many anti-cellulite treatments out there, like Velashape (which Kim Kardashian underwent on Keeping up with the Kardashians), Zerona, etc., all of which are non-invasive, utilizing ultrasound waves, laser therapy, or a combination of the two.
