You know why Rachael Ray is smiling all the time? She's the richest food star in the world. According to the latest Forbes list of top-earning celebrity chefs, Rachael Ray leads the pack. In fact, of the top 10 names, all but two are TV stars.

Therefore, you better believe that all that exposure on Food Network, Bravo, Travel Channel, Fine Living, BBC America, and Fox -- not to mention syndication and appearances on talk shows and demonstrations on the Today Show -- makes a big difference.

The richest man in the world has a secret. He likes to watch the goings on in Pine Valley. You know, the place Erica Kane -- Susan Lucci, don't you know -- calls home. And now he's going to be on his favorite ABC soap, too -- for the second time! Billionaire Warren Buffett will play himself on All My Children during May sweeps.
