Dr. Ayham Al-Ayoubi, a London-based plastic surgeon, posted a side-by-side comparison photo of the superstar on his Twitter page, with the implication that she had undergone some cosmetic procedures.
One side shows a fresh-faced woman resembling Jennifer with no makeup, while the other side is a picture of the entertainer in full makeup.
He wrote: "These before and after pics of @JLo show many signs of #plasticsurgery - naturally pretty but now looks amazing."
Rather than ignoring the accusation, the 44-year-old singer responded, saying: "@DrAyoubi Sorry Sir, but I have never had plastic surgery of any kind. #fact."
Jennifer has been plagued by cosmetic surgery rumours for years, but the naturally beautiful star has been flawless ever since we can remember.
Don’t just take our word for it, though: Scroll through the gallery below for photos of Jennifer throughout the years!
