Katy Perry hat sunglasses dress Urth Cafe necklace

Actually, that's her BFF Markus Molinari, so don't worry - Katy isn't stepping out on her Brit beau! But from the skinny jeans to the unruly brown locks, he totally resembles Russell, and these two were spotted all over the place this weekend! First they shopped at Kitson and caused quite a commotion with photographers, and then the duo stopped by Urth Caffe to refuel.

So what was Russell doing while his lady love was out with his twin? Oh you know, just hanging out on his balcony in a pair of bright blue manties!
