Kelly Clarkson's free concert to celebrate the grand opening of the new Microsoft Store at the Walden Galleria this Saturday (November 16) has been postponed!

Microsoft and The Walden Galleria released this statement:

Following Kelly Clarkson’s Thursday night concert in Tennessee, she became ill. Unfortunately, Kelly will be unable to perform at the scheduled Microsoft Store concert on November 16. The show will be rescheduled in the next few months and specifics will be announced later by Facebook, email and other channels.

Fans are still able to line up at the Microsoft Store beginning TONIGHT (Friday, November 15 at 10 p.m.) for a chance to win tickets to the postponed performance. The first 100 fans in line receive a ticket and meet & greet, and the first 1,500 will get a ticket to the show. Fans should line up indoors in the corridor between Coach and Sephora; enter at Cheesecake Factory.

We'll keep you updated with the new details as they become available.
