Unless my eyes deceived me, Britney Spears is seen in a silver RX8 at the beginning of her latest video. You probably have to watch it on a satellite channel as they show videos right from the beginning. No vidcaps for you, sorry. Interesting that she could have easily chosen a £150,000 supercar.

There's a couple of threads about this including a downloadable copy of the full video.

If you know TV production well enough, it's probably chose by the Executive Producers. They are the one who's got the say.
