Report: Katherine Heigl Will Return to Grey's Anatomy

at .

The Season Six cast of Grey's Anatomy is becoming clearer by the day.

Following reports that original cast member T.R. Knight is leaving the series for good, a fact that has been long-rumored but finally confirmed this week, comes an inside source confirming to E! Online that Katherine Heigl "will be back" next season.

Heigl had been said to want off the show for an entire season.

Official comments from the show bosses or Katherine Heigl has not been issued, however, E! is one of the more reputable celebrity news sources around, so if we were forced to take a guess as to this story's legitimacy, we would believe it.

Izzie in the Afterlife?

Season Five ended on a double-death cliffhanger, as T.R. Knight's character, Dr. George O'Malley, struggled to survive massive trauma inflicted by a bus accident, and Heigl's Dr. Izzie Stevens was enduring life-threatening complications of her cancer treatment.

One could say that the split decision - T.R. Knight goes and Katherine Heigl stays - was sort of telegraphed in the fifth season finale's episode-ending dream sequence.

In that scene, Izzie seemed drawn back to the voices of friends trying to save her life, while George seemed serenely ready to move into the new phase of existence.

What do you think? Are you happy Katherine is coming back? Do you not believe anything until you see her on screen in the Season Six premiere?
