Britain's Prince William has teamed up with soccer idol David Beckham to record public service announcements (PSAs) for wildlife conservation charity WildAid. The pair filmed the commercials on Thursday (12Sep13) as part of the non-profit organisation's demand reduction campaign, which is aimed at reducing the demand for rhino horn and ivory in places like China and Vietnam. The advertisements will air later this year (13). Prince William recorded the PSA hours before attending the inaugural Tusk Conservation Awards at the Royal Society, London on Thursday (12Sep13). The event marked his wife Catherine, Duchess of Cambridge's first red carpet appearance since giving birth to their first child, son George, in July (13), and she dazzled photographers in a glittery floor-length gown by designer Jenny Packham.
