Princess Di Underwear Ad Has Brits in Snit She's barely dressed ... and why is she playing a cello?

(Getty Images) (Newser) – A lingerie company in China found an odd way to mark the Aug. 31 anniversary of Princess Diana’s death: with an ad showing the beloved Di in a bra and underwear. Jealousy International’s ad for “Diana underwear” (yes, really) uses the tag line, “Feel the romance of British royalty,” and is running on billboards in China. In addition to her skivvies, the young Di—or a lookalike—is shown with … a cello. I “couldn't quite believe what I was seeing,” a British journalist, who saw the ad at an airport in China, tells the Daily Mail. “I thought, surely not, because it was rolling quite quickly. So I waited to check when it came up again and, sure enough, there was an image of Diana.” Click here to see the ad.
