Paris Hilton has refused to pose naked in Playboy - despite having already bared all to the world in her leaked sex tape.

The sexy socialite - who unintentionally starred in X-rated home movie 'One Night In Paris' - says Hugh Hefner is desperate for her to feature in his famous magazine.

Hugh Hefner wants to be buried next to Marilyn Monroe. The Playboy founder has had an ornate vault earmarked alongside the screen goddess at Los Angeles' Westwood Ceremony - because he thinks she is "the major sex symbol of the 20th century."

The 79-year-old magazine mogul - renowned for his love of blondes - thinks the plot next to the "Some Like It Hot" star is the ideal final resting place.
