The 'Dark Horse' singer tweeted she was present for a home birth earlier this week, and the bundle of joy is believed to belong to her older sister, Angela Hudson.
"Finally, you can add 'helps delivers babies in living rooms' to my resume! It's been a miracle of a day...Auntie Katy aka Stylist Auntie," Perry, 29, tweeted.
Perry didn't elaborate on the identity of the mom or baby, but since she only has once sister, Angela is a fair guess.
