Contract BREACH......this time round is KIM Kardashian.

Kardashian, 33, was reportedly paid $500,000 to attend the prestigious event in Austria as the guest of Richard Lugner, an Austrian businessman, but she opted to leave early after a man wearing "black face" began mimicking her fiance Kanye West, according to TMZ.com.

Lugner accused the E! star of failing to fulfill her contractual obligations as his "date."
"Kim is annoying me because she's not sticking to the program," Lugner was quoted as telling reporters –celebritywatchdog.blogspot.com
Kardashian, who was accompanied by her mother and manager Kris Jenner during the gig, reportedly stayed for an hour and a half before storming out of the event. The mother of one was prompted to leave after a second man allegedly made a tasteless joke about West's hit song "N----- in Paris."
E! camera crews were reportedly present to capture footage of the event for Kardashian's hit reality TV show "Keeping Up With The Kardashians." Lugner, who is renowned for hiring celebrity dates to the ball, also complained about the filming.
"She's filming and so she doesn't want to have me around," he said. "The guest should be with me and not anywhere else that is not agreed upon."
Earlier in the day Kardashian was photographed fulfilling a number of scheduled appearances alongside the 81-year-old European tycoon. The reality star appeared for a photo call at the airport and at his Lugner City mall.
Kardashian, who has made several trips to Europe in recent months, has not publicly addressed Lugner's complaints.
The E! star has been busy traveling between the U.S. and France in preparation for her upcoming wedding to West, 36. The Hollywood power couple will wed in Paris during the summer.
"It's just insane ... Kanye has basically billed it as … breaking the boundaries of what to expect when it comes to a wedding," a source told Heat magazine U.K.
"This will be the event of the year," the insider continued. "Think fashion runway, stage show performance. Think avant garde. Think nothing like you've ever seen.
