Elvis grandchild won't be 'dumb twit' like Hiltons

Lisa Marie Presley has vowed she will never allow her daughter to turn into a "dumb twit" like socialites Paris and Nicky Hilton.

Presley - daughter of Elvis and actress Priscilla - has boasted that unlike the hotel heiresses, her 15-year-old daughter Riley is the perfect example of a well-brought up child who doesn't dress or act like a "tramp".
