Experts' predictions had Sandra Oh taking home the Best Supporting Actress honors, but when the dust settled, the Emmy went to Katherine Heigl!

Katherine, who was not only going up against the formidable Sandra Oh and a third Grey's Anatomy star, Chandra Wilson, but three of the best supporting actresses from all other drama series, was quite taken aback.

Katherine Heigl, who won in her first-ever Emmy nomination, joked that she did not prepare a speech for the occasion because "My own mother told me that I didn't have a shot in hell of winning tonight."

As cameras focused on her mother and manager, Nancy, in the crowd, Katherine Heigl laughed and added, "But she's a really big supporter. She does love me."

In closing, a tearful daughter addressed a tearful Nancy Heigl, "This is for you, this is because of you. I wouldn't want to be here without you."

Congratulations to Katherine, and to Sandra and Chandra on their nominations!
