On Wednesday, the "Dark Horse" singer took to Twitter to announce that she had a new thing to add to her long list of accomplishments.
"Finally you can add 'helps delivers babies in living rooms' to my resume!" Perry tweeted. "It's been a miracle of a day...❤️ Auntie Katy aka Stylist Auntie."
While the 29-year-old star didn't reveal the identity of the person she helped, E! News reports that it was likely her sister, Angela Hudson.
Perry's tweet came a day after it was widely reported that she had ended her on-and-off relationship with John Mayer yet again. A moving truck was spotted outside the singer's Los Angeles home earlier in the day.
