Last year, Lifetime announced that Jewel would star in a biopic of June Carter Cash. Now we have video evidence that Ring of Fire is real! In this clip, we see Carter join her first husband, Carl Smith, onstage at the Grand Ole Opry for a folksy comedy bit and a song. (Here's the real Carter and Smith doing a different but similar number.) The jury's still out on Jewel's acting abilities, but the singing and outfits seem festive enough.
