She has envious curves, beautiful facial features and is one of the most searched names on Google. Many people see her as an epitome of perfection.  But Kim Kardashian, the 32-year-old reality TV star, looks unhappy after her image was used for the promotion of plastic surgery in Mexico and is apparently threatening to sue the company.

Kim is rumored to have gone under the knife more than once (but she vehemently denies it). She asked her lawyers to go ahead after an image of hers lying on a sunbed in a bikini was used on a billboard for Dr. Victor Ramirez in Mexicali.

The billboard was accompanied with a slogan that read: No arriesgue su belleza, ni su salud', which translates to Don't risk your beauty or your health. The idea propagated is to encourage people to visit a professional plastic surgeon and not risk their health by visiting an unsafe one, reports the Daily Mail.

When TMZ contacted Dr Ramirez and asked if he had sought Kim's permission before using her image, he apparently said he did not, because I don't have her number.  

When TMZ told him that using someone's image in an ad without permission was an offence, he said he would involve the police.

Kim denies having undergone any surgery for either her curvy bottom or for her luscious lips. However, there are many before/after images of the sex tape fame celebrity which show the difference between her figure before and after surgery.

Talking about her implants and plastic surgery rumors, Kim said: Rumors don't bother me anymore. I've read that I've had my lips done. I've always had big lips. Look at my baby pictures. It's ridiculous. Or they'll show one picture of me today and one tomorrow, and say I've had my nose done in between. When? Didn't you just see me yesterday?, reported facenfacts.com.

And how many times have I 'had my butt done'? People's logic is so weird. I don't know why they bother! she added.
