Katy Perry's decided it's time for a Wednesday war against the tabloids.

It's all to do comments she made earlier in the week about product placement in music videos.

Marina Diamandis (from Marina and the Diamonds) Tweeted: 'What is consensus on product placement in videos? As a fan, do you prefer product placement if it means bigger buget vid?'

Katy replied: 'do it w/style & grace...Not so in ur face like some. U hv to get creative w/it.Some artists don't care tho, & u can tell'.

It was seen as a reference to Britney's use of products in her 'Hold It Against Me' video but Katy's not impressed with how her comments have been interpreted.

In a string of tweets today she says,

"Dear tabloid media aka FILTH: pls note I expressed an overall feeling bout product placement, their roles in vids & the art of them being...complimenting or sticking out. Most, if not ALL popsters welcome deals w/products 2 offset costs of big budget vids in these recessional..music industry times. I'VE used them in MY vids before & am happy 2b able 2 make a better vid because of. Once AGAIN, stop pitting artists..against artist for ur sensational satisfaction & stick to what ur best @: lying, gossiping, exaggerating & overall lending a hand 2 the....deterioration of a generation."

Katy's just kicked off her California Dreams tour - you can see the pictures from Lisbon, Portugal below.
