Well I would say there are similarities, but I doubt she was inspired by it.
All of the stuff Gaga did for BTW's promo and what Katy's doing for Roar is just logical marketing.
And I know Gags wants to go with the more ~subtle~ promo after she got dragged for her BTW promo, but people are only just realising she's even back, where as katy's promo is much more effective.
Be shameless Gaga, get back to prostituting your album everywhere
