Perry posted a photo of the Shakey's marquee (not the Santa Monica location, but now is not the time to be picky) which read, "Happy Birthday Katy Perry, From Sophia," and captioned the snapshot, "KICKING OFF BIRTHDAY WEEK RIGHT! This signage is a bucket list dream come true!!! SHOUT OUT TO ONE OF MY BEST FRIENDS FOR KILLING THE GIFT GAME @rivfifi"
The Sophia mentioned is Sofia Rossi, co-founder of Hello Giggles and legendary friend. She also posted the picture and wrote, "BETTER EVERY THAN NEVER @katyperry !! Happy Birthday DESPERATE."
