So, it comes as no surprise to people that there are some celebrities who really are obsessed with plastic surgery. When you think about plastic surgery in fact, you might even automatically equate it with the Hollywood lifestyle. While some celebrities look better for it, there are others who just look ridiculous.

Perhaps one of the most notable celebrities (if that's what you want to call her) who is obsessed with plastic surgery is Joan Rivers. The woman must be in her seventies now, and it's obvious she's tried to look like she's forever in her thirties. No, she doesn't look her true age, but she doesn't exactly look natural either. Specifically, her face is forever frozen in ghastly smile. No wonder she decided to make fun of the work she's had done.

The most drastic example of plastic surgery is the case of Jocelyn Wildenstein, a socialite. She started off looking quite attractive, but then decided to ruin all that by looking like a cat. So, she had her face restructured. Yes, now she looks quite feline, but she also looks quite ridiculous too.

Another celebrity who, though not obsessed with cosmetic work but still looks silly, is Kenny Rogers. He always taught us that "You gotta know when to hold 'em, know when to fold 'em". However, it's obvious that he didn't know his limits when he got a facelift and ended up looking too smooth. It can't be a good thing to look like you're perpetually surprised, can it? Luckily, he's said that he's going to have his face fixed again.

Of course, who could forget Cher? She doesn't look horrible, but she's definitely trying too hard to reclaim her youth. She's clearly had facial implants and face lifts to augment her already exotic features. Take a look at early Cher, and compare her to the present-day Cher. Didn't she look better before?

A case of cosmetic work that might or might not have happened is Sophia Loren. She's in her late sixties now, but she looks even better than she did when she was in her twenties! She says she credits her good genes for her youthful appearance. However, that doesn't stop people from thinking that she's had work done. Whether she has or she hasn't, she looks fabulous.

The key to good cosmetic work is to have it done, but to keep people guessing like Sophia Loren has. The best cosmetic results are the ones that look the most natural. You want to turn back the clock a decade at most – not fifty years like some celebrities have attempted to do. So, if you're considering having a procedure done, you definitely should check out the surgeon's portfolio first. After all, you want to look better, not worse!
