Poor Katy Perry! She's so sick she had to cancel her show and apologize to her fans.
Perry is currently on tour in Europe, but had to pull out of a scheduled concert in Milan earlier this week due to influenza. Yikes!
In a post on her Twitter page, Perry says, "To my Milan fans, so sorry the flu hit me here in ur (sic) beautiful city. I'll make it up to you, promise. Looking for reschedule date now."
She later uploaded a photo of herself in a hot bath eating some pizza, in Spain. KP-" I have no self control"
Perry is now in Barcelona where she's scheduled to perform at the U18 Festival tonight. But she's still so sick, she doesn't know if she'll be able to perform tonight either. She updated her MySpace.com page to read, "Sick in Spain."
