One fan said she was "bummed out" about the news. And we'd imagine a large number of other concert goers feel the same way.

Nevertheless, as finalists from American Idols Live kicked off their U.S. tour Wednesday, this season's runner-up, Katharine McPhee, was nowhere to be seen. She was sidelined with severe bronchitis and laryngitis.

Those in Manchester - at the Verizon Wireless Arena - won't get to see this talent perform. Organizers announced that McPhee's doctor, Sean Nassari, ordered "total voice rest."

The starlet, of course, didn't want to let down her fans. In a statement, she said she was disappointed she couldn't perform, but "I need to follow my doctor's orders to recuperate and reunite with the rest of the Idols."

Amen, Kat. Feel better soon.
