According to E! News the 35-year-old Keeping Up With The Kardashians star won't host Hakkasan Nightclub inside Sin City's MGM Grand on October 28.
The same site added that the wife of Kanye West has been getting counseling after experiencing flashbacks after she was held at gunpoint and robbed of $11 million worth of jewels in Paris.
She is apparently contractually obligated to appear four times this year at the club, collecting $1 million for her trouble.
The cancelled gig, in the wake of her October 21 birthday, would have only been her third. No fourth appearance is listed on the venue's online events calendar.
However, citing sources from Hakkasan, E! News claimed the club has its eyes fixed on a smooth rapport with the reality star and her family, and will let her shift the event to a new date without a pay cut.
