Mert + Marcus may be doing the next string of Louis Vuitton ads, but Annie Leibovitz has reunited with the monogrammed brand for yet another upcoming campaign shoot, according to reader Christopher. On December 20th, Louis Vuitton rented various areas of the Regency Hotel in New York for their latest commercial, directed by Ms. Leibovitz and produced by Karen Mulligan. We hope some behind the scenes footage of the shoot can eventually leak online, especially since Louis Vuitton just posted a slew of scenes from their Mert + Marcus shoot online, with Marc Jacobs and Naomi Campbell describing the production, and Zoe Cassavetes creating the footage. The last round of Leibovitz + Louis ads starred old school actress Catherine Deneuve and Russian icon Mikhail Gorbachev. Maybe this new slew has Gwyneth.
