Katy Perry & John Mayer Celebrate Fourth of July Together!

John Mayer rehearses on stage for the Philly 4th of July Jam Concert held as part of the Welcome America Festival on Thursday (July 4) in Philadelphia, Penn.

The 35-year-old singer was joined for the day by his on-again girlfriend Katy Perry, who posted a photo of themselves embracing backstage on her Instagram account.

“Whose broad stripes & bright stars?!” Katy captioned the photo. She also tweeted a photo of her patriotic nails, which you can see below!

There were some reports that the pair would be spending the day in the Hamptons, but those were incorrect as they were in Philly for the concert.
