When it comes to supporting her choice for the next president, Katy Perry backs her girl in a way only she can. With a controversial costume ahead of a giant concert.

The singer hit the stage Wednesday night for the Hillary Victory Fund I'm With Her Concert at Radio City Music Hall in New York.

The Clinton supporter looked like an ultra-chic Uncle Sam donning a patriotic ensemble complete with stars and stripes.

Perry also performed many songs, including a rendition of America the Beautiful that might give you the chills.

Before singing Wide Awake, she seemed to ask an enthusiastic audience if they were committed to Team Hillary.

"Are you wide awake yet? Do you need to see anymore, or are you wide awake yet?"

Perry rocked a black and white short-sleeve shirt that is the definition of a statement tee while signing autographs outside Rockefeller Center hall.

Also seen outside the famed venue? Orlando Bloom.

The pair was spotted vacationing in Hawaii, holding hands on a romantic hike. We'd had an inkling a relationship was building since a few shots of a close encounters surfaced after the Golden Globes, and are hoping their love will bloom. See what we did there?
