Bombarded with questions

It appears my mother's quiz magazine has posed what she refers to as "some real stinkers". As the font of all knowledge I of course get hit with them as I dropped her off this morning. Give them a go yourself:

Paris Hilton's sister?
Lisa-Marie Presley's mother?
Marilyn Monroe's playwright husband?
Star of "Wild at Heart" now part of a talent show?

The answers being -

I don't know
Priscilla Presley
Arthur Miller
Amanda Holden

A quick search reveals the answer to the first question is Nicky. I'll let her know this afternoon.
