It's been a long held dream of many men to see Cheryl Cole and Katy Perry together. Well, it finally happened yesterday. Did they engage in a pillow fight? Did they mud wrestle? Did they maybe practice a little bit of kissing? No, of course they did not. They just judged The X Factor. Disappointing.

Katy was serving as a stand-in judge for Dannii Minogue, who is somewhere having a baby and being too lazy get up and tell some people they can't sing and the fact their entire family died in a fairground accident is never going to to change that. Well excuse us, your majesty.

Given the two extraordinarily attractive elements, this post is probably kind of a let-down. But Katy, who is going the extra mile to look even hotter than usual right now, at least turned up looking pretty mind-blowing.

We're not really sure how to end this story...so, erm, then they woke up and it was all a dream.
