Oprah Winfrey tweeted a picture of herself walking across hot coals a few days ago, with the caption reading: “Me! Fire-walking! Last night!”

In the picture, you see her literally walking across the hot coals, under the supervision of famed life coach, Anthony (Tony) Robbins. You can also see Sheri Salata, Oprah’s executive producer in the background. People speculate that this will be part of ‘Oprah’s Lifeclass’ series.
