Abby Stern is the author of "According to a Source," the new novel that fictionalizes her long career as a Hollywood insider. The book stars Ella Warren, a celebrity reporter who comes face-to-face with the gossip industry. Along the way, she copes with a demanding boss, and questions whether joining Hollywood's inner circle is worth the collateral damage. Abby tells us how to craft the perfect blind item that gives readers just enough information on a celebrity without actually identifying them. Then we play 'Blind Item Billionaires,' Cheddar's spin on the technique, where we challenge Abby to name Silicon Valley's hottest movers and shakers based on a small juicy blind item.
