What's the latest for Callie, Arizona, Lexie, Mark, Alex and April on the Grey's Anatomy romance front? We've got your answers here, thanks to creator Shonda Rhimes.

The show-runner says that despite revelations in sneak previews for tonight (brought on by Jessica Capshaw's pregnancy) Callie and Arizona are in it for the long haul.

“Their journey is going to be long and hard, but that doesn’t mean they’re not going to end up together,” she said. “People better just prepare for things to be difficult.”

Would she put Mark and Lexie in that same soulmate-type category, though?

“No,” she said, before quickly adding, “That doesn’t mean that I don’t see them as two people who are going to end up together… There’s hope for Mark and Lexie."

"[However] Lexie has some growing up to do, as does Mark.”

Sounds like those hoping for a Mexie reunion may not want to hold your breath. Lastly, what about the new rumor going around about an Alex-centric love triangle?

“I honestly have no idea what [fans] are talking about,” responded Rhimes, denying that one flatly. “We have absolutely no plans for an Alex-April-Lexie triangle.”
