While at the Vienna Opera Ball on Thursday, February 27th Kim Kardashian's big night out turned into a nightmare when a man in blackface approached her during the event and pretended to be her fiancé, Kanye West.

According to Us Weekly, the 33-year-old who looked gorgeous wearing a dramatic two-tone gown with sheer detailing on both the bodice and skirt was busy posing for pictures with her date, Austrian businessman Richard Lugner, when the incident took place.

TMZ, which was first to break the news reported that another man came up to her and asked her to dance to "N****rs in Vienna," which was a twist on her boyfriend turned fiancé's song with Jay Z titled, "N***as in Paris."

North West's engaged mom, Kim Kardashian has not commented on the incidents nor has her mother Kris Jenner, who accompanied her to the Opera Ball.

However, the matriarch from the "Keeping Up with the Kardashians" family did take to Instagram to share a photo of the packed ballroom. Attached to the snapshot was the caption, "Wanna Dance?"

According to Us Weekly, the "Vienna Opera Ball is an annual society event that takes place at the Vienna State Opera in Austria. Lugner has a history of paying celebs to be his date to the function; his past guests have included Pamela Anderson, Carmen Electra, Paris Hilton, and Dita Von Teese."
