Kelly Clarkson is currently on the road with her Stronger 2012 Tour, and the way her tour dates are structured, she gets a day or two off between shows. Over the weekend during one of her off days, Kelly appeared on stage during a show in Colorado with East Texas' own Miranda Lambert.

Miranda and Kelly are both appearing on The Voice this year as Blake Shelton's mentors for his team and have been friends for quite some time.  Kelly told the crow she has always seen parts of a Miranda show, but never the full thing until this night.

Miranda introduces Kelly before taking the stage and the crowd lets loose with a ton of screams and the two perform Kelly's latest hit "Stronger (What Doesn't Kill You)".
