‘American Idol’s Lionel Richie reveals anti-aging secrets: ‘Sex’

For Lionel Richie, “Endless Love” that lasts “All Night Long” might be his secret to endless youth.

The 73-year-old “American Idol” judge revealed his tricks for staying fresh-looking, after stunning fans with his youthful appearance during a performance at King Charles’ coronation concert on May 7.

The “Stuck on You” singer told the Daily Mail that his anti-aging secrets include “water, sleep, sweat and sex.”

“I know it’s real boring. [Sex] will work also, and it’s good for your heart,” he said.

Richie also added that he and his 33-year-old beau Lisa Parigi also avoid eating too much red meat.

The “Lady” singer made the revelation after a few fans speculated that the crooner may have gone under the knife.

“How is Lionel Richie 73, he looks so young,” gasped one fan.

“Surely, Lionel Richie didn’t need those cheek fillers or the plastic surgery,” said a second Twitter user.

A third social media user joked that whoever performed the surgery “should have their license revoked.”

Richie denied the accusations, telling the outlet, “[Plastic surgery] locks you in for that year [while you recover] — and after that, you can’t go naturally, you’re staying right there… You try and go back to reset, and you can’t.”

According to the singer, he would never get plastic surgery because “that s – – t goes wrong” and “God might not recognize me.”

The Post has reached out the Richie for comment.

Richie, who sang “Easy” and “All Night Long” for the new brand-new monarch in front of 20,000 people, left fans seriously divided over his vocals.

Several people compared the performance to the Muppet Kermit the Frog or that of a karaoke singer in a bar. Other Twitter users defended the singer and blamed the issues on the sound equipment.

The “American Idol” judge was not the only celebrity to perform that night.

Fellow “Idol” judge Katy Perry, 38, also made an appearance on the stage after him and belted out a few of her own hits.

British pop group Take That and former Pussycat Doll Nicole Scherzinger, 44, who claimed to be having a real “Disney princess moment” while singing a song from “Mulan,” also performed over the course of the night.
