Katy Perry unveiled her latest single Walking Up in Vegas on American Idol’s results show last night, and showed some love for mascara meister Adam Lambert. During her performance she flashed a Bedazzled Adam Lambert inscribed cape, which probably made Glambert wet/shit/peepee his pants all at the same time. Lambert has cited Perry as one of his favorite performers–and Perry’s unlikely Idol-producer-unapproved endorsement will score him some 2CoOl4SkEwL points with all the 10th grade girl viewers out there!*~!*~!*! But how awesome is this new single and how hot is her Elvis-look? Sorry for the fuzzy vid, but YouTube Nazis take down the best quality stuff.
