Kimora Lee Simmons puts on a brave face to attend the grand summer premiere of the “Carnevale” Festival held at the Venetian Hotel and Casiino in Las Vegas last evening June 11.

The appearance comes after author and former Osama Bin Laden’s mistress Kola Boof took to twitter and blast the fashionista saying she is the reason Kimora and hubby Djimon Hounsou have ‘split’ and she did it as “revenge” for Kimora’ cruel treatment of her.

“I am not in love with Djimon Hounsou & he is not in love with me,” she wrote. “The only reason I had sex with him was to get revenge on Kimora….Kimora nearly destroyed my life and my children’s lives,” the author claimed. “She is a lecherous, two-faced, money-obsessed witch and a delusional snob.”

I’m not doing 80 post on this drama – perhaps Bola has some kind of agenda because she has a book out and is tweeting about gaining new followers and book sales up?!… if you’re interested in reading more about this mess, read here, here and her twitter page here
