Transformers babe Rachael Taylor will be guest starring on the next new episode of Grey's Anatomy (airing February 3rd) as Callie's obstetrician. But, we've heard whisperings that things get pretty hot and heavy between her and Karev. She hasn't quite dished on how far the fling goes, but she confirmed that the two were spending a lot of time together on set.

"I'm working with Justin Chambers a lot," says Rachael. "Justin's hilarious. He has a wicked sense of humor."

When pressed for more deets, she deftly deflected, claiming she doesn't get scripts until a week before the shoot. "I don't know. There's been no steam yet, I don't think..." she teases. "Depends what you call steam."

As for the rest of the actors on set? They've all been perfectly behaved, says Rachael. "I wasn't sure what to expect from the cast, but they can't have been more gracious or welcoming," she gushes. "Ellen Pompeo is like the sweetest woman in the world — she's so delightful. Patrick is a gentleman. They've all been wonderful. And it's really impressive as well that seven years on they show up, know their lines, put in great performances and also have the energy to welcome a newbie like me. I didn't expect it."

Sounds like that tense phase of working on the show really is over. And, apparently, all those rumors about Ellen Pompeo secretly being a huge be-yotch on set are totally unfounded. Good to know!
