Because she's being goofy?
That's why I mentioned "major studio" release
Katy Hudson is a Christian music album released in 2001 when she was still Katheryn Hudson, when she was 16 The label that released it got suspended a few weeks later and the album didn't even sell 200 copies, 200 is an exaggeration.
After this, she moved to LA and changed her name to Katy Perry (her mother's birth name). She started writing songs by herself during which she was dropped and signed by 3 labels She rose as a background vocalist and some of her songs went to other artists like Kelly Clarkson Her last label introduced her to Max Martin and Dr Luke and finally she released her debut studio album One Of The Boys, with some selfwritten songs
Katheryn Hudson's debut album was Katy Hudson. Just think of it as you recording some songs in your garage and releasing it for your church.
Katy Perry's debut album was One Of The Boys - a major studio release with the singles I Kissed A Girl and Hot n Cold.
Why else do you think her upcoming album is called KP5 by the mass and not KP6?
I know y'all didn't ask for this but just putting it out there
