Kelly Clarkson looked amazing for NBC’s “Christmas at the Opry” special. Clarkson’s form-fitting holiday gown shocked fans. The 41-year-old sang “Santa Claus is Coming to Town” with Wynonna Judd as they opened the show.  Kelly wore a gorgeous emerald green waist-flowing dress with see-through long sleeves that sparkled; it was the talk of X, formerly Twitter.  One fan tweeted: “Need @kellyclarkson’s green metallic #christmasattheopry outfit immediately!! Where can I buy one…not that I can afford it…#HaveIEverSeenABetterDress?”
