Singer and actress Jennifer Lopez adressed rumors that suggested she had gone under the knife by claiming she's all natural. It all began when a plastic surgeon wrote on Twitter that the 44-year-old star looked amazing after surgery, Latina reported.

"These before and after pics of @JLo show many signs of #plasticsurgery - naturally pretty but now looks amazing," tweeted London-based plastic surgeon Dr. Ayham Al-Ayoubi, according to NY Daily News. He included a split-screen picture of the singer, one showing Lopez with make up and the other where she can be seen with a fresher face.

The "On The Floor" singer also took to the popular networking site to denied the rumors. "Sorry Sir, but I have never had plastic surgery of any kind. #fact," she wrote.

According to Latina, the plastic surgeon replied with, "Dear @JLo I wonder if you can accept my sincere apologies about the wrong tweet which was written by my assistant without my knowledge..." Lopez gave no response to his tweet.  

On a second tweet, the surgeon wrote, "I sincerely apologize to @JLo & her fans. I want to remind everyone it was NOT me who sent that wrong tweet! It was my assistant."

Lopez seems to be pretty confident about her body. During an interview for the October edition of Cosmopolitan magazine she confessed her biggest insecurity was her singing.

"The biggest insecurity I had was my singing. Even though I had sold 70 million records, there was this feeling like, 'I'm not good at this.' And while I was married to Marc [Anthony], he helped me get over it," she told Cosmopolitan, according to E! Online. "He kept telling me, 'You're the only one holding yourself back from reaching your full potential as a singer. You have to let go.'"

The mom of two realized her hard work was definitely paying off. "I was always so insecure and just kind of going along," added Lopez. "Then I grew, little by little, and realized, 'Wait a minute, this is not a fluke. I'm not a mistake--I work my ass off. And I know what I'm doing.'"
