Each year, Barbara Walters hosts a special on ABC, interviewing the people that she deems the most fascinating people of that year. This year's show will air on December 6 and will feature Justin Timberlake, Jennifer Hudson, and Grey's Anatomy star Katherine Heigl as part of the 10 Most Fascinating.

Katherine Heigl certainly had an eventful year that put her in the spotlight. She starred in the movie Knocked Up with Seth Rogen, winning critical acclaim and doing extremely well commercially. She also won the 2007 Emmy Award for Outstanding Supporting Actress in a Drama Series for her portrayal of Dr. Izzie Stevens.

Katherine Heigl also got engaged to singer/songwriter Josh Kelley, and their wedding is scheduled to take place next month, just before Christmas.

Of course, part of what makes Katherine Heigl fascinating is also controversial. While the rest of the Grey's Anatomy cast was tight-lipped during the infamous Isaiah Washington incident(s), Heigl was outspoken regarding the matter. Katherine has never been afraid to be anything but herself, that's for sure, for better or for worse.

Besides Heigl, Walters will also speak to Victoria and David Beckham, as well as former President Bill Clinton, the two masterminds behind MySpace, and many more. Last year, Barbara Walters dubbed one of Heigl's co-stars one of the most fascinating people of 2006 - the talented, handsome Patrick Dempsey.
