Marlon Brando's son CHRISTIAN allegedly sold his late father's address book of celebrity contact details to a mystery buyer. PageSix.com reports the buyer then tried to sell the Rolodex on online auction eBay before Christian's brother MIKO used his contacts to get the item removed from the website. The address book is believed to contain the phone numbers, email addresses and home addresses of more than 100 of the world's most famous political and entertainment figures. Celebrity agent Richard Smith refuses to reveal the identity of the buyer, but he tells PageSix.com, "Christian sold it to an individual who had placed it on eBay."
