As Grey's Anatomy anxiously await the fates of cast members T.R. Knight and Katherine Heigl and whether their characters, George O'Malley and Izzie Stevens, will be back season, another original star of the show is nervous about her own status.

Well, probably not really. But Chandra Wilson, who plays Dr. Miranda Bailey on the hit ABC show, is still waiting to re-sign her contract to come back for a sixth season.

"You know, I don't have the slightest idea!" the actress, who is starring in Chicago this summer, told The View when asked if she knew who was leaving. "I know nothing!"

In fact, she said that she still hasn't received word on whether she'll be back on the show: "I'm waiting for my Disney letter saying, 'You have the option to come back.'"

The company has until June 20 to send it, she added.

We can confidently say that hell would freeze over before the series would let Wilson go, but her coyness indicates that even fellow cast members likely have no clue what's going to happen with Knight and Heigl. Whether Knight and Heigl even know is a mystery!

Reports of George's demise vary - and have lingered for months, culminating in a gripping season finale in which he and Izzie were literally in between life and death.

Grey's Anatomy creator and executive producer Shonda Rhimes hasn't divulged any information on next season's cast or story lines. All we can do is hope for the best.
