Chris Brown was forced to cancel his Burswood Dome concert in Perth last night at the last minute due to illness. The singer caught the flu, which later turned into a bacterial chest infection. Brown is offering a full refund to his fans.

Originally, Breezy had planned on letting the show go on, as he initially tweeted, "I haven't been sick like this in a while!!!! F**k it though! I'm still doing the show in Perth!" But later, the 21-year old singer tweeted a "Sick Face" picture to his followers, and wrote a message explaining his doctor's orders. "Still feel like s**t. Doctor told me I had the flu and it turned into a bacterial chest infection. Super meeds!," he tweeted. In the photo, CB looked worn out while laying on his bed.

Still, despite CB's apologies, some fans are not happy. MTV UK is reporting that one ticketholder said it could take up to 2 weeks to get his money back, while others thought the canceled performance was a joke. The show will not be rescheduled.
