Kelly Clarkson couldn't wait to take the stage at the CMA Music Festival in Nashville last Saturday. However, while she was in the middle of performing, the singer realized her $150,000 engagement ring was missing. She even apologized to her fiancé Brandon Blackstock who was watching backstage. However, just a day later, Kelly tweeted that her rings had been found. Phew! We can't imagine how nervous that made both of them! We bet she never takes those rings off ever again!
