Katy Perry celebrated Halloween early over the weekend by visiting Knott’s Scary Farm, and the pop star took extra measures to make sure she wouldn’t be recognized — by painting her face into a skull. (Nice way to one-up all the other pop stars with their skeleton couture!) Tweeted Katy, “Be honest with me, do I look tired?” Less so than in this pic, at least. Head below to see another photo of Katy and Russell Brand incognito, though to be honest, we’re not sure which costumed chap he is.
