In his new revealing expose, Overexposed: The Price of Fame, Eliot Tiegel explores the inevitable and sometimes dangerous, media-frenzied draw toward Hollywood stars -- and he's telling ET how the increased paparazzi coverage of today is affecting starlets Lindsay Lohan, Paris Hilton, Nicole Richie and others.

"The rule is that if you're in the magazines you're alive and the public will know who you are," Tiegel explains about celebrities in the media. "Once you're not doing anything and you fade away from all these tabloid magazines who fight every week to produce the same stories most of the time, you disappear -- which means you're not popular anymore."

Tiegel also discusses the death of Princess Diana in 1997, caused by a car accident that followed a paparazzi chase in the streets of Paris.

Watch the video to hear Tiegel discuss how the paparazzi attention has changed entertainment journalism, and he explains the commodity behind star photographs -- an undeniable incentive for getting the perfect shot.
