It's back to work for Carrie Underwood, three months after giving birth to her son, Isaiah Michael Fisher.

Underwood gave her first live performance since welcoming her baby at the Grand Ole Opry in Nashville Tuesday night (June 9), joining fellow Opry members Bill Anderson and Del McCoury for a special show that served to kick off the Opry's CMA Music Fest Week schedule. Billy Currington, Easton Corbin, Scotty McCreery, Mickey Guyton, and Mo Pitney were also on the bill for the special performance.

Afterward, the seven-time Grammy winner hosted her annual Carrie Underwood Fan Club Party backstage as part of the tradition of the CMA Music Festival, which brings fans from all over the world to Music City for some face time with their country music heroes.

The evening was special in more ways than one for Underwood, coming just one day before the tenth anniversary of her debut Opry performance, which took place on June 10, 2005, less than a month after winning American Idol. In the decade since then, Underwood has become one of the most respected and successful artists in contemporary country music, winning virtually every major award, scoring 14 No. 1 hits and playing the biggest arenas in the world in concert. Underwood recently celebrated the first ten years of her success with the release of a hits collection titled Greatest Hits: Decade #1. She is slated to perform at the CMT Awards on Wednesday night (June 10).
