Lizzo quit Twitter after her online beef with Dr. Boyce Watkins, who claimed her popularity was due to the "obesity epidemic in America."

The "Good As Hell" singer announced she was quitting Twitter just one week into the New Year.

"Yeah I can't do this Twitter s--t no more," she tweeted before adding, "too many trolls. "I'll be back when I feel like it."

Lizzo's followers assumed she quit due to her run-in with Watkins, an author and financial expert.

On Dec. 20, Watkins wrote:

"#Lizzo popular is because there is an obesity epidemic in America. 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."

The "Juice" singer clapped back, saying her immense "talent" was behind her widespread popularity.

"I'm popular because I write good songs and I'm talented and perform high energy hour and a half shows filled with love," Lizzo fired back. "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."

She added: "Here's the attention you ordered."

According to industry insiders, Lizzo tips the scale at 280-300 pounds and she has obesity-related health problems that caused her to cancel recent concert dates.
