We've been debating this week whether Izzie could be pregnant on Grey's Anatomy. We have our doubts, but according to EW's Michael Ausiello, there is another Izzie surprise in store for us soon. Meanwhile, Richard's stress apparently boils over tonight.

Here's what EW's spoiler Q&A reveals this morning ...

Q: Is Izzie really pregnant on Grey’s Anatomy?

A: I'll say this: ABC's promo gurus are very sneaky! While we’re on the subject of Katherine Heigl, sources confirm that she’s taking another leave of absence from Grey’s Anatomy this season - but this time her reasons are personal and not professional.

Heigl will be going on a belated maternity leave to spend some QT with new adopted daughter Naleigh. As a result, Izzie will be MIA for another string of episodes (most likely in early 2010).

What do you think prompts Izzie's second departure from SGH?

Q: Please tell me something will happen soon on Grey’s Anatomy that will make me stop hating the Chief! I used to love him but this season has been terrible!

A: Would the sight of him falling off the wagon do the trick? 'Cause that’s what happens at the end of this week’s episode, "New History."
