There was a scary moment during the Los Angeles stop of Oprah Winfrey's 2020 Vision speaking tour.

At the beginning of the Saturday event, the 66-year-old media mogul shared some words about wellness and the importance of a balanced life. 

"Here’s my definition of what wellness means to me," she told the crowd at the Forum arena. "Wellness to me means all things in balance. And balance doesn’t mean all things are equal or at peace at all times—"

Before she could finish her thought, Oprah lost her footing and took a pretty hard tumble, prompting attendees to collectively gasp. Oprah quickly made a joke out of the situation, stating "Wrong shoes!" into the mic.

Oprah switched into sneakers after the fall, and continued the event with special guest Jennifer Lopez. Oprah thanked the 50-year-old entertainer in a tweet Saturday night, while also referencing her now-viral slip.

"Thank you to the astoundingly age-defiant @jlo who came to the show in this stunner & gave new meaning to the word 50," she wrote. "LA: You were lit! In spite of my fall (which now becomes a meme), you brought me UP with your energy. Now I’m headed home to ice my knee."

50 Cent was one of the many people who re-shared he video. And, to no one's surprise, he used the incident to make fun of Oprah.

Fif has criticized the multi-hyphenate for her role in the #MeToo movement, claiming she never condemns alleged predators who are white, and only focuses on the accused black men—specifically Russell Simmons and Michael Jackson. 50 alluded to his criticism in an Instagram post that included footage of Oprah's tumble.

"What the fuck happen here, 🤦‍♂️😆," he captioned the clip. "Michael Jackson's ghost trip her."
