The Mean Girls star and her sister, who wore Nazi uniforms, were dressed as the Nazis during the party, which took place at a New York City mansion owned by the Duggars, sources told TheWrap.
The party was held at a mansion owned and controlled by Duggarlos Dukes, a.k.a. the Dukes of Hazzard, a family of Hollywood celebrities and reality stars who are well-known for their extreme views on the occult and other occult topics.
The Dukes attended the party at their family home in the exclusive Queens neighborhood of Williamsburg, according to sources familiar with the party.
TheDukes, who are married to actor Michael Dukes and have two children, had been scheduled to be at the party on Thursday, but were not invited, a source familiar with Dukess schedule told The Daily Beast.
“The Duggarts wanted to get the party started and were happy to have someone like them on the house.
They also wanted to have the party in their backyard,” the source said.
“We understand the Dugs have strict rules, but it was a huge hit and they ended up staying.”
Sources say the party was meant to promote their upcoming movie Mean Girls.
The Duggards are set to star in the movie, which is being produced by the same production company that produced Mean Girls, according the source.
The movie, based on the 1987 novel by Nancy Kaczynski, revolves around a high school student named Megan who gets into a relationship with a former high school teacher, a girl named Emily.
The film, which will be produced by 20th Century Fox, is expected to hit theaters in 2018.
