Bret Michaels announced on Twitter that his show is cancelled tonight, November 11th,  due to a medical emergency. Bret and his band were scheduled to play a sold-out show in Greeneville, TN.

The news came out a few hours ago from his personal Twitter page. The post said the following:

With much regret, we hate to inform you that tonight's Bret Michaels sold-out performance will be postponed due to a medical emergency. Bret has an incredibly large kidney stone and several small stones that are now in a position that have made Bret immobile. While kidney stones are extremely painful on their own, being a diabetic complicates the situation and Bret needs to be monitored very carefully.

We wish Bret the best of luck and hope he can get back to playing live very soon. We will continue to follow this story and provide updates as soon as we learn more info.
