While fans of Grey’s Anatomy have been left to speculate on the future of original cast members Katherine Heigl and T.R. Knight, some of their co-stars are no better off.

Access Hollywood caught up with Jessica Capshaw, who plays Dr. Arizona Robbins on Grey's, to as if she had any insight on the respective futures of Izzie and George.

“I will absolutely be quoted as saying [series creator and executive producer] Shonda Rhimes is an absolute genius because she doesn’t tell anyone anything,” Jessica said.

Not knowing what lies ahead is just fine with Jessica.

“That’s actually very generous of her because she doesn’t want to burden us with knowing and not being able to tell you – or telling you!” the actress added.

The beautiful, talented Jessica Capshaw.

However, Jessica’s own future with the show also remains up in the air – she revealed she has yet to receive her renewal letter (although ABC has until June 20 to send it).

“Knock on wood,” she said.

The 32-year-old actress, who joined the show in its fifth season, was hopeful she would be returning to Seattle Grace, along with the rest of the Grey's Anatomy cast.

“It’s fantastic. It’s funny that there’s so much drama surrounding the show, because you’ve never met a group of more decent people,” she said. “It’s as normal as it gets.”
