Looks like it was literally a pink friday for ‘Last Friday Night’ singer Katy Perry.  Donning a flowing Alexis Mabille couture dress and Christian Louboutin, the pop eccentric was billed to tribute Sir Paul McCartney at the 2012 MusiCares Person of the Year Tribute (singing Beatles’ hit ‘Hey Jude’) last night. The L.A. Convention Center-hosted bash also guested music stars Corinne Bailey Rae, India Aire, and Alicia Keys who, like Perry, signed on for entertainment duties at the esteemed gala.

The event certainly comes as one of many both Keys and Perry are readying for as both have been confirmed performers at the 54th annual Grammy Awards airing tomorrow night!  Until their highly anticipated showings, get into the ladies below:
