Katy Perry knows how to rock a stage unconditionally.

After all, the singer wowed at the MTV VMAs 2024 – hosted by Megan Thee Stallion— on September 11, where she delivered an impressive, high-profile performance that included a medley of many of her chart-topping hits. And the 39-year-old shared an unexpected secret about the performance with her fans in the first line of her acceptance speech for the Michael Jackson Video Vanguard Award.

“Thank you,” she told the cheering crowd, “I did all this on the first day of my period, can you believe it?” (For more moments you may have missed on TV, click here.)

During her performance, Perry wore a sculpted nude body armor and black briefs with over-the-knee boots. She began the 9-minute rendition by flying through the air while singing her hit song “Dark Horse.” The aerial acrobatics continued for several minutes as she soared over the heads of her dancers while singing her otherworldly single “ET.”

Once on the ground, the singer of “Woman’s World”, who has a 4-year-old daughter Daisy Dove with her long-time fiancé Orlando Bloom– kept her energy up, running and sliding across an inclined platform while belting out her hits like “Teenage Dream,” “California Gurls,” “I Kissed a Girl,” “Firework” and more.
