Former SEINFELD star Julia Louis-dreyfuss is stopping traffic on Hollywood's Sunset Strip with a saucy new billboard campaign. The actress appears on huge posters on both sides of the boulevard, advertising her new TV show THE NEW ADVENTURES OF OLD CHRISTINE, cheekily showing off a pink thong. The ad, which reads, 'Grin... and wear it,' features Louis-Dreyfuss - who plays a divorced mum trying to find a sexual partner in the new show - contemplating wearing the sexy lingerie, and then showing the thong riding out the top of her jeans. The actress' new show debuted in America last night (13MAR06).
