Katy Perry is not impressed with the “in your face” product placement in fellow pop star Britney Spears latest music video ‘Hold It Against Me’.The ‘California Gurls’ hitmaker jumped into a debate on Twitter, started by British singer Marina of ‘Marina and the Diamonds’ who posted the question, “What is consensus on product placement in videos? As a fan, do you prefer product placement if it means bigger budget for video (sic)?”Perry slammed Spears’ recent advertisement-friendly video, tweeting, “Do it with style and grace… Not so in ur face like some. U hav to get creative with it. Some artists don’t care tho and u can tell (sic).”Spears reportedly made a whopping half a million dollars from product placements in her new music video. From cosmetics to a dating website, companies paid her a combined total of $500,000 to feature their items in the four-and-half minute video, reported TMZ.Besides the ‘Toxic’ hitmaker, another artist who recently made an advertisement-friendly music video is Avril Lavigne.The 26 year-old pop punk singer makes use of her ‘What the Hell’ clip to promote some Sony electronic products as well as her own products including Black Star perfume and Abbey Dawn clothing.
