Some celebs love having their picture taken, and some go out of their way to run for cover. In Katy Perry's case, we kinda understand, because she had just gotten off of a plane and she wasn't wearing any makeup. For everyone's sake, it's probably best that we didn't get a pic of the 30-year-old singer, but we're just wondering how she can see where she's going!

On Friday night Katy landed at Los Angeles International Airport, and while she seemed a bit shy here, it sounds like she's ready to roar if she gets dissed in Taylor Swift's new music video, "Bad Blood"! "Both Katy and John are ready to watch it and they are ready to be unimpressed,” a source tells HollywoodLife. “They are not scared of any diss that might take place, but Katy is secure in the fact that if a major diss happens, she will gladly have a rebuttal in either a future video, song or performance."

Can't wait to see how it all goes down tomorrow when the video premieres at the Billboard Music Awards!
