I listen to a lot of KP. A LOT. I have a 3.5 year old and that is all she let's me listen to. I'm just happy to finally be able to move beyond the third track (California Gurls).
Katy's style is super fun. It's definitly a diva style and not necessarily to be tried at home but I do love the vintagey feel and think I have touches of that in my own style.
Rock on Katy!
