Joining the list of celebrities, who have stripped for the controversial PETA advertisements, is model-actress Olivia Munn, whose nude poster was released on Thursday. Shot by renowned celebrity photographer Emily Shur, the poster shows Munn posing nude with a tagline: Who Needs Fur To Feel Beautiful?

A fully nude image was initially chosen to appear on billboards, but due to the fact that it was too risqué, a partially nude photo will appear on the PETA billboard in Beverly Boulevard in Los Angeles.

Though the latest celebrity nude poster from PETA doesn't come with the shock element, there have been several instances where the organization drew considerable amount of flak for adolescent advertising which drew more controversy than drive home a point.

Here is a list of PETA's most controversial publicity stunts:

1. Veggie Sex Super Bowl Commercials - The PETA commercial released in 2009, featuring scantily clad women, caressing and rubbing vegetables against their body, powerless to resist the temptation of veggie love, was rejected by the NBC for the Super Bowl. The video was banned due to women rubbing pelvic region with pumpkin, screwing herself with broccoli, and depicting a level of sexuality exceeding NBC standards. However, PETA cashed in on the huge amount of publicity generated probably due to the ban.

2. BDSM Sex Stunt - There isn't anything unusual about PETA being against training and torturing animals for human entertainment. However, the organization sparked controversy by launching a campaign Whips and Chains Belong in the Bedroom, Not in the Circus. The campaign included street demonstrations in New York and Cincinnati, where PETA activists dressed up like people inclined towards violent sex or BDSM, sporting whips and chains, and whipped each other. The street campaign, as well as the poster, featuring Indian model Sherlyn Chopra, generated a huge amount of publicity, but PETA drew criticism for indulging in mindless publicity gimmicks.

3. Holocaust on Your Plate - The graphic publicity campaign and exhibit of 2003, Holocaust on Your Plate sparked worldwide outrage, in which PETA juxtaposed 60-square-foot panels showing gruesome scenes from Nazi death camps alongside disturbing images of animals from farms and slaughterhouses. Among those who slammed the campaign was the Anti-Defamation League which denounced the comparison of animal slaughter to the murder of 6 million Jews in World War II. PETA's effort to seek approval for their 'Holocaust on Your Plate' campaign is outrageous, offensive and takes chutzpah to new heights, the League said in a statement.

4. KKK Stunt - The PETA campaign of 2009, in which activists dressed as Ku Klux Klan members protested against dog shows and the American Kennel Club (AKC) dubbed Klux Kanine Klan by the organization, drew criticism for being insensitive and inappropriate. Obviously it's an uncomfortable comparison, PETA spokesman Michael McGraw had said, adding that the AKC is trying to create a master race when it comes to pure-bred dogs, which makes it a very apt comparison.

5. Breast Milk Ice Cream - PETA's decision in 2008 to pitch the idea of using human breast milk in ice creams to the world famous ice cream makers Ben & Jerry's raised many eyebrows due to the social, ethical, legal and financial problems associated with commercializing something like breast milk. Ben & Jerry's said the company does applaud PETA's novel approach to bringing attention to an issue, but we believe a mother's milk is best used for her child. However, the ice cream, named Baby Gaga, became a reality in 2011, after a London ice cream manufacturer Matt O'Connor launched it in market.
