We reported last week that Katy Perry would be opening for No Doubt for one show only — August 4th in Irvine, California. If you want the best seats for the show, then make sure you buy presale tickets, which go on sale tomorrow at 4 PM local time. A link to where you can get the tix, as well as the password, is all available at KatyPerry.com. Tickets go on sale to the general public this Saturday at noon Pacific.
