Oprah's embarrassing moment

Even the mighty fall sometimes.

During the L.A. stop on her 2020 Vision tour,Oprah Winfrey tripped and fell on stage -- while talking about finding balance in her life.

A fan caught the embarrassing moment on video and shared it on Twitter.

In the clip, Oprah says, "Wellness to me means all things in balance, and balance doesn’t mean all things are equal or at peace at all times." She then takes a few steps, stumbles and crashes to the stage.People magazine reports that boyfriend Stedman Graham rushed to the star's aid, as she joked, “Wrong shoes.”

Oprah did the rest of her talk barefoot.

She talked about the fall in an Instagram video. She said, "I didn't even think 'embarrassing.' I just thought 'Okay I fell, everybody knows what falling is.' You would prefer not to fall, but now I've fallen."

Jennifer Lopez was the special guest at the event.
