Katy Perry is looking hotter than ever! The singer has been attending music functions all weekend with boyfriend John Mayor (and looking stunning we might add) and wore a bright orange Alexander McQueen dress to the MusiCares Person Of The Year event to honor Bruce Springsteen. We're loving the sequned detail on this neck and her smoky eye, but we also can't wait to see what she's going to be wearing for the Grammys!

Katy finished her look with Guiseppi Zanotti shoes, Judith Leiber bag, and Lorraine Schwartz jewels.
