Did Katy Perry Help Deliver Baby in a Living Room?

On the same day that news was spreading about Katy Perry's reported breakup with John Mayer, the pop singer tweeted about helping deliver a baby in a living room.

While Katy didn't provide many details about the apparent at-home birth, she did describe the event as miraculous. 

It's not known who the baby was that "Auntie Katy" helped deliver, but many of Katy's fans are speculating that the mother is her older sister, Angela, who was expecting a child.
