Jennifer Lopez isn't keeping silent. After a U.K doctor claimed that the singer/ actress had already gone under the knife, J.Lo defended her natural beauty vehemently by posting on Twitter that she has never had surgery.

Dr. Ayhan Al-Ayoubi, who identified himself as a facial plastic and laser surgeon in London, sent out a tweet Monday claiming that Jennifer Lopez has already undergone plastic surgery. 

"These before and after pics of @JLo show many signs of #plasticsurgery - naturally pretty but now looks amazing." Al-Ayoubi tweeted, together with two photos of J.Lo - one, seemingly without make up.

While it doesn't seem like Jennifer Lopez is judging those who already had their bodies scientifically improved, she did clarify that her sexy body and beautiful face isn't a product of surgery.

Lopez, not taking the upfront lie, decided to step in through her social media account and slam the doctor for her false accusations, reports E! News.

"@DrAyoubi Sorry Sir, but I have never had plastic surgery of any kind. #fact," she claimed.  

J.Lo's claims doesn't seem to be unrealistic. As a matter of fact, there are many celebrities that are in their forties that look really much younger even without going through surgeries. Gwen Stefani, at 44, is still looking fine for her age. Jennifer Aniston, who turned 44, is another classic example of youthful ageing - she still looks like she's in her late twenties.

Aside from returning as judge on American Idol, J.Lo also recently launched her latest business venture at Baldwin Park in California. 

Back in October, Latinos Post reported that Lopez partnered with Verizon Wireless to form the premium provider known as Viva Movil. Launched just a few days ago, Lopez serves as founder and co-owner of the premium phone retailer alongside Brightstar and Moorehead Communications.
