On Tuesday, the 44-year-old entertainer took to Twitter to deny claims from a London-based plastic surgeon that she’s been under the knife.

According to reports, Dr. Ayham Al-Ayoubi tweeted on Tuesday, “These before and after pics of @JLo show many signs of #plasticsurgery – naturally pretty but now looks amazing.”

The post reportedly showed a split-screen photo Jennifer — one showing her with make up on and another of the singer au naturel.

The mother of 5-year-old twins, Max and Emme, matter-of-factly responded:
