THE PRESIDENT OF MARC JACOBS COMPANY ROBERT DUFFY POST A PIC ON TWITTER OF A NAKED MAN ON A POLE @ A MARC JACOBS AFTER PARTY & GETS HIS ACCOUNT DELETED!

Marc Jacobs head honcho Robert Duffy has caused quite a stir since developing a recent addiction - to Twitter, that is.

Duffy (who has amassed 6,700 followers on the social networking site) has spilled the beans the past week about almost everything relating to Marc's highly anticipated show Monday, including pictures of some of the collection and the set, and specific instances of "model drama."

But the prez of Jacobs' company may have crossed the line when he snapped a pic of a very naked man who looked like he was pole dancing at Jacobs' after-party on the 18th floor of the Standard Hotel Monday night.

The tweet, which has since been deleted from his page, was replaced by one yesterday morning in which Duffy apologizes: "The pic of the guy from the party was taken down because Fr-d didn't want it up anymore. I thought it harmless. His wife didn't. Sorry."

Duffy wasn't alone in enjoying the goings-on: We hear that Rachel Zoe, Bee Shaffer and Jacobs' hubby Lorenzo Martone were enjoying the, err, festivities as well.

While that incriminating pic (who we assume was of an entertainer named Fred) was removed, Duffy posted other party pics on his page, including a not-so-flattering shot of him and Jacobs at the bash.

After several of Duffy's followers commented that Jacobs, who had his eyes closed in the picture, looked inebriated, Duffy took to his page once again.

"NO [Marc] wasn't drunk in that picture," he tweeted. "He was happy and giving me a kiss. Be nice please."

Given his affinity for TMI, perhaps it's better that Duffy didn't join Jacobs the rest of the evening. As the businessman tweeted a goodnight to fans, we hear the designer kept the party going.

Spies at hot spot Avenue say Jacobs joined Julie Henderson at the Supermodels Doing Good event around 2 a.m., where the likes of Kellan Lutz and AnnaLynne McCord (who came and left separately) and Russell Simmons continued to fete the fashionisto.
