Ellen Pompeo

Estimated off-set earnings: $700,000
She may be the title character, but the most iconic thing about Meredith Grey, and by extension Pompeo, is her voice. According to one advertising executive, her distinctive voice may be her most valuable asset, because when it comes to choosing Grey’s docs for beauty campaigns, Katherine Heigl and Kate Walsh are almost always top-choice. A 2007 Propel Fitness Water television commercial voice-over earned Pompeo approximately $200,000. But other than the 2006 New York & Co. campaign with Dempsey ($500,000), her only other endorsements have been unpaid: A huge sports fan, Pompeo has done a number of spots for Major League Baseball. She has not made any films since Grey’s Anatomy premiered in 2005.
