INHERITED: Athina Roussel, granddaughter of the late Greek shipping tycoon Aristotle Onassis, becomes one of the world's richest people Wednesday simply by turning 18, at which point she comes into her share of the family fortune, estimated to be $2.7 billion in properties, companies, stock, artwork and a private jet.

SELECTED: TV vet John Ritter, 54, now starring on ABC's "8 Simples Rules for Dating My Teenage Daughter" (and who cut his teeth in the 1977-84 sitcom "Three's Company"), will host the inaugural "TV Land Awards: A Celebration of Classic TV," reports Variety, which says that the special will recognize shows that have withstood the test of time.

SNUBBED: Peter O'Toole, 70, who was to receive an honorary Academy Award at the March 23 Oscarcast, has informed the Academy that he doesn't particularly want it. In a handwritten open letter to the Academy, the seven-time nominee says he was "enchanted" by the group's gesture, but said that since he is "still in the game and might win the lovely bugger outright, would the Academy please defer the honor until I am 80?" On Tuesday, Academy president Frank Pierson, hoping O'Toole might change his mind, told Daily Variety: "We will have the Oscar for him and if he cares to pick it up, that would be great."
