Joan Rivers Says Prince William And Kate Middleton Won't Last

Prince William Kate Middleton Just in time for the Queen's big Jubilee bash, Joan Rivers takes a swipe at Prince William's marriage to Kate Middleton on The Late Show. Her prediction: time is ticking for this fairytale union.

The death knell for this royal marriage, according to Joan, is that ring! Yes — that diamond and sapphire beauty weighing in at a hefty 18 carats.

Almost in one breath, the comic with perpetual foot-in-mouth disease explained to David Letterman why she thinks the royal couple is doomed for failure.

"Here's a girl he's in love with, 'Sweetheart, I want you to have my mother's ring,'" Rivers said, channeling the prince. Sounds like a nice sentiment, right — giving your sweetheart your late mother's ring?

But it's not a nice sentiment, according to Rivers, when your mom was Princess Diana and your parents' relationship fell apart for all the world to see.

"My mother and father hated each other, they think my brother was somebody else's, my mother was crazy on drugs, tried to kill herself... good luck!" Rivers told Letterman and audience.

Eighteen carats or not , Rivers said that ring would be a deal-breaker for her.

Rivers' comments come 13 months and some change since the Royal Wedding was shoved down our throats 24/7. So Rivers really isn't giving the couple much time to settle in to the union. But, then again, that length of marriage in celebrity years is like a quarter of a century in "regular people" years.

These characteristic comments are also coming at a time when Joan is making the media rounds, publicizing her new book, I Hate Everyone… Starting With Me.
