London: Singer-actress Jennifer Lopez insists she has never had any plastic surgery.

The 44-year-old singer hit back after a British plastic surgeon, Dr Ayham Al-Ayoubi, suggested she "showed many signs" of having work done to her face, reported Femalefirst.

"These before and after pics of JLo show many signs of plastic surgery - naturally pretty but now looks amazing," Ayham posted on Twitter.

She responded to the plastic surgeon, who is based in London, saying, "Dr Ayoubi Sorry Sir, but I have never had plastic surgery of any kind."

But following Lopez and her fans` reaction, the medic claimed his assistant was responsible for the tweets.

"Dear JLo I wonder if you can accept my sincere apologies about the wrong tweet which was written by my assistant without my knowledge...," he wrote.

The `American Idol` judge had recently revealed that she learnt to stand up for herself from an early age as she was criticised for her appearance and curvy figure early in her career.
