Is Katherine Heigl Leaving 'Grey's Anatomy' Again!?

Katherine Heigl

Katherine Heigl just got back on 'Grey’s Anatomy''s set (after taking a three-month maternity following the adoption of her 15 month old daughter Naleigh) and she is already rumored to leave the series. "It wouldn't be a shock", says a source.

The reason? The 31 year old actress who'll be soon rewarded with the ShoWest award for Female Star of the Year seems like she wants to focus on her big screen movie career.
Katherine Heigl started playing in ABC’s hit medical series in 2005 and she was the one always saying when something was going wrong on the set. For example, in 2007 after she won a supporting actress Emmy, the actress withdrew her name from Emmy contention because she "did not feel that I was given the material this season to warrant an Emmy nomination". In July of 2009, while invited in David Letterman's show, when asked about returning to the Grey’s set, she said: "Our first day back was Wednesday and it was — I’m going to keep saying this because I hope it embarrasses them — a 17-hour day, which I think is cruel and mean". We like her for telling what she thinks.
As for her role as Dr. Isobel Stevens in 'Grey’s Anatomy', we'll see. So far Heigl’s representative nor ABC made any statement in that matter.
