Izzie Stevens returns to Grey’s Anatomy this week ... but is she alone?

No, we're not talking about her high school mentor. We mean is she pregnant?

The new promo for this week's "New History" certainly implies that she is ... or does it? Is it just another deceiving promo, a classic Shonda Rhimes mind game at work?

It will be interesting to see who Meredith is directing her "You’re pregnant?" at ... and whether it's even true. Remember Rose's "I'm pregnant, Derek ... kidding!" Exactly.

If Izzie were in fact pregnant, the timing could be fortuitous for the put-upon Dr. Stevens.

As series creator Shonda Rhimes told TV Guide, “Izzie has had everything taken from her - she’s had cancer, she’s lost a friend [George], and she had what she saw as a betrayal of a relationship [with Alex] when she got fired - so she’s sort of standing on this very delicate place where she feels like she has nothing left to live for."

"She’s searching for some reason to hang on.”

What do you think? Is she knocked up, or is this just misdirection?
