Katy Perry changes into medical scrubs as she leaves a building following an appointment on Wednesday (July 22) in Los Angeles.

The day before, the 30-year-old entertainer called out former friend Taylor Swift for her comments to Nicki Minaj about the VMAs.

Katy also expressed her frustration that Rihanna wasn’t nominated.

“The real travesty is where is the shine for #BBHMMVideo when VMA eligibility period was 7/7/14-7/1/15 & that gem dropped 7/1… @MTV,” she tweeted.
