When Kellie Pickler performed in Effingham, Illinois - Gregg Lohman's hometown - late last week, he joined her for the gig with no prior warning. The singer was stunned and overcome with emotion.

In a post on her Facebook.com page, she writes

"I cannot even describe how beautifully overwhelming (the) show was. Not only were the people amazing but I also witnessed a miracle. Many of you know about my drummer Gregg and the horrible car accident he was just recently in... He has never missed a show in the seven years he's been with me..."

Little did Kellie know as Gregg was going to surprise her by playing drums for the encore song Red High Heels. Continues Kellie:

"When I hit the stage and saw that Gregg was now sitting behind his drum set I fell to pieces. It was special moment for me as well as my band and crew."

Gregg is still undergoing physical therapy as he recovers from his injuries.
