Katy Perry wore the American flag’s famed stars and stripes on her chest while commemorating the Fourth of July on Thursday.

The “Firework” singer celebrated the holiday with a sizzling new Instagram snapshot in which she wore a bedazzled red, white, and blue bathing suit top and emulated Rosie the Riveter’s classic “We Can Do It!” poster posture.

Katy Perry recreated Rosie the Riveter’s “We Can Do It!” poster pose for the Fourth of July.

The “Firework” singer also promoted her forthcoming single, “Woman’s World.”

“BB UR A FIREWORK ,” Perry, 39, began her caption, before promoting her forthcoming single, “Woman’s World,” which drops July 11.

“And speaking of work, WOMAN’S WORLD IS GOING TO WORK IN ONE WEEK HAPPY 4TH .”

The upcoming track marks Perry’s highly anticipated return to music and follows her recent appearance at Paris Fashion Week last month.

Perry has been heavily promoting the song, which marks her return to music, after she stepped down as an “American Idol” judge in May.

She previewed a snippet of the song’s lyrics on her dress at Paris Fashion Week last month.

The former “American Idol” judge gave fans a preview of the song by putting some of the lyrics on the extra long train of her red velvet Balenciaga dress last month.

Though the exact words were difficult to make out on the 200-foot train, fans speculated that the dress read, “It’s a woman’s world and you’re lucky to be living in it / Sexy, confident / So intelligent / She is heaven-sent / So soft, so strong.”

Others guessed that more lyrics included, “Fire in her eyes / Feminine divine / She was born to shine.”

“It’s a woman’s world and you’re lucky to be living in it / Sexy, confident / So intelligent / She is heaven-sent / So soft, so strong,” the dress read, per fan theories.

Perry’s single is set for release on July 11.

Perry debuted her new song shortly after leaving her role as a judge on “American Idol” after the 22nd season.

Before leaving, she paid respect to 168 “Idol” competitors by placing their faces on her maxi skirt from the May finale.

“I thought a good way to honor my time here would be to put the top 24 of each season on my skirt so they were all there,” Perry told “Entertainment Tonight” at the time, before touching on the moment she got to show off the look on stage. “It was a fun surprise because I was raising up and you just saw more and more contestants.”
