Paris Hilton and new boyfriend Benji Madden are super keen to let us know their relationship is for real, so maybe that's why they've started co-ordinating their outfits, like this his-n-hers hat action they showed off at Maestro's Steakhouse in Beverly Hills. They should look to Posh and Becks for inspiration, as the British couple have been rocking the whole matching outfits craze since this leather look from 1999! What I want to know is: are matching clothes only OK on celebrities? Or can we do it too?!
