Katherine Marie Heigl (born November 24, 1978) is an Emmy-winning and Golden Globe-nominated actress best known for her role as Izzie Stevens in hit tv series Grey's Anatomy and movies Knocked Up and 27 Dresses. She recently topped this year's list of Askmen's 99 Most Desirable Women beating heavy favorites Jessica Alba, Eva Mendez and Keira Knightley.

Heigl was once in a relationship with Roswell costar Jason Behr. In June 2006, she became engaged to singer Josh Kelley, whom she met on the set of his music video for “Only You.” The couple was married on December 23, 2007 in Park City, Utah. For their honeymoon they escaped to the plush Esperanza resort in Cabo San Lucas.

At the end of 2007, Barbara Walters named Heigl one of the “The 11 Most Fascinating People of 2007 ” on an ABC/DEF program of that title. Heigl questioned her inclusion on the list, saying that in fact she is actually “quite boring…..not, just kidding, but really”.
