Actress and former model Katherine Heigl is well known for her starring roles in Knocked Up, Grey's Anatomy and 27 Dresses. Heigl was born in Washington on 24 November 1978 to parents Nancy Engelhardt and Paul Heigl. She's one of four children. She's been married to Josh Kelley, an American singer-songwriter, since 2007, and the pair now have three children together.
Along with her highest profile small screen success to date, Grey's Anatomy, she starred in the comedy film Knocked Up alongside Hollywood comedian Seth Rogan which brought her a lot of media attention. In an interview with Vanity Fair, Heigl called the movie "a little sexist", and said that the film "paints the women as shrews, as humourless and uptight, and it paints the men as lovable, goofy, fun-loving guys". This brought her some negative media attention, but at least Heigl was honest about this and mentioned the obvious negative stereotypes of women in comedy films that are common in Hollywood.
Katherine Heigl has recently joined the cast of the incredibly popular TV series Suits.
Katherine has been using e-cigarettes since just before her interview with David Letterman more than five years ago. She used her e-cigarette on the show and then urged David Letterman to try it too. He said that the device was "remarkable!".
