Kristin released a new chat tonight...it's pretty interesting. Callie has something in common with Paris Hilton (uh-oh)? They're bringing on two new series regulars? Geez. And so much more, so read on for the scoop...

Have they completely dropped the storyline of a main character being bisexual on Grey's Anatomy?
Looks that way.
How's it looking for Addisex on Grey's?
Not good. Aside from the Addison & Alex scoop I spilled in my new Vine show, things with "Crush" will heat up over the coming episodes. I met Elizabeth Reaser at the Independent Spirit Awards, where she was nominated for Best Female Lead for Sweet Land, and she's simply fabulous. When I told her about the fan nickname for her Jane Doe character on Grey's—Crush, because Alex has a crush on her and because she was crushed under that pylon—she completely wigged. "Are you serious? I have a nickname? I'm…I'm totally dorking out right now." Naturally, I pried about her 10-ep stint on Grey's, and she told me, "It was scary, but then I got on set, and they're just the nicest people, and they welcomed me, and Justin Chambers is just such a sweet guy. I'm very lucky. I think I've only done four episodes so far, though. I have no idea what's going to happen—and if I tell you, and I don't tell my sister, I'd be in so much trouble!" Okay, fair enough, but the minute your sister knows—call me.
Are they still going to reveal that a character is bisexual on Grey's? It's been forever now since you told us that!
I know, and apparently, I really should have kept my big yapper shut, because much like the what-the-dog-saw-in-the-cargo-hold reveal from the first-season finale of Lost, it seems that my reporting (among other factors, I'm sure—I hope!) of this storyline caused it to be changed. The original plan was to have a female character's past love come back—and that love was a woman. But now this female character will have a past love come back—and it is a man. Still, it will have ripple effects in this character's current relationship.
So Addison's leaving Grey's… maybe. Are we gonna get a new character to take her place?
Well, I don't know if "take her place" is the right terminology, but I can tell you there will be a new series regular on Grey's very soon. Two, in fact! My sources tell me that one of them will be a female doc who's around the same age as Addison. She'll be African-American, and I'm told her name might be Naomi. I'm also hearing about a young guy named Dell who's very cute and could be joining Olivia at the nurses' station!
You mentioned Callie has a big secret on Grey's. Any hints? Please, please, please?
Sure. She has something in common with Paris Hilton.
Are Izzie and Alex the two interns hooking up on Grey's Anatomy? Please tell me I'm right!
Nope, sorry. You're not.
