Katy Perry films birth on phone

THE  ‘Roar’ hitmaker was by her older sibling Angela Hudson’s side last week when she welcomed her little girl into the world, and although she helped deliver her niece, the 29-year-old pop star still managed to capture the moment on film.

Katy – real name Katherine Hudson – said: “My sister had a baby in her living room – very naturally, not one Advil. I was there kind of being an assistant doula and saw everything. We had dinner first, obviously before I saw it all. It was an incredible experience. I was kind of like Martin Scorsese with my iPhone – I have the whole thing. It was like a water birth, and we’re like ‘The child is swimming through the water.’ It’s crazy.”

After witnessing the birth, Katy went on to hail mothers as ‘real rock stars’. The ‘Dark Horse’ singer – who recently split from boyfriend John Mayer after 18 months of dating and who was previously married to Russell Brand – said: “It’s insane – whenever I see moms walking down the street I’m like, ‘Damn, you’re a rock star, you’re the real rock star – you did something incredible.’ ”

And Katy admitted her entire family is excited by the arrival of Angela’s baby, especially her parents Keith and Mary Hudson. Speaking on the Fifi & Dave Show on Australian radio station Fox FM, she said: “The baby girl is so alert and aware, and active and incredible. It’s the first time we have a little one in our family one so everyone’s very excited.”
