Lizzo decided to let Dr. Boyce Watkins have it after he commented on her body positivity message via Twitter. Earlier this month, the academic and media commentator sent out a tweet assessing why Lizzo was popular.

“Lizzo is popular is because there is an obesity epidemic in America,” he wrote. “Rather than encouraging people to do better, we are simply lying to them and telling them that they are just fine the way they are. Unfortunately, many of these people are dying from diabetes and heart disease.”

On Monday (December 23), the pop superstar got wind of Dr. Watkins’ tweet and responded on Twitter.

“I’m popular because I write good songs and I’m talented and perform high energy hour and a half shows filled with love,” she wrote. “The only person who needs to do better is you. Keep my name out ya mouth & look in the mirror before you come for me. Here’s the attention you ordered”

Dr. Watkins replied to the body positive activist with a video via Twitter on Tuesday (December 24), throwing singer-songwriter India Arie into the mix. In the clip, he compares the two singers and asks viewers which woman they’d rather have their daughters “grow up to become.”

Lizzo has yet to respond to his latest post.

Despite Dr. Watkins’ comments, the entertainer has been riding high off her Saturday Night Live debut. The episode, featuring the return of SNL alum Eddie Murphy after 35 years, became the highest-rated episode for the late night sketch show since 2017.
