Russell Brand and Katy Perry
There's absolutely nothing low-key about Russell Brand and Katy Perry. The mop-topped comedian acted alongside Katy Perry in the film Get Him to the Greek, and later flirted with the pop singer while hosting the 2009 MTV Video Music Awards. Since they've hooked up, the two have been inseparable. Brand told Britain's GMTV, "It was a deep craving within me – I mistook it for lust. I thought I was promiscuous, but it turns out I was just thorough – to get the right one. I'm ever so happy."
