I am completely and utterly embarrassed that I missed this – but, apparently, Joan Collins’ son wrote a book.  Amongst the dishy details revealed in Sacha Collins’ Unaccompanied Minor, he makes quite an accusation against his father, Anthony Newley.  “He was a pedophile.  My father was drawn to youthfulness.  He thought innocence was an aphrodisiac.  That was his sexual proclivity, and it’s a very dangerous, destructive thing.”  Well, Miss Collins is having none of it.  She went on a UK morning show and said, “I think that Sacha’s being extremely naïve and not really knowing the meaning of that word.  Because what Tony admittedly was is he loved young women – and young women of 17, 18, 19 years old.  Not children by any means.”  You say potato…
