Easter eggs are things hidden in an artist's songs, videos, etc. that are references to his past work, controversies, etc. that only hardcore fans will know.
In Katy Perry's music video for Roar, after the tiger has been defeated by Katy, a collar is seen on its neck with a pendant with the name 'Kitty Purry'. That is the name of Katy's pet cat.
Does your fave also have easter eggs hidden in her work? Post some!
