Rachael Taylor will appear on Grey's Anatomy's next new episode in the intriguing role of Dr. Lucy Fields, a major character's obstetrician, according to TV Guide.

You can see her in action in this photo gallery from February 3's "Don't Deceive Me (Please Don't Go)." But there's more to her role than just treating Calliope.

"I'm working with Justin Chambers a lot," says Taylor of the actor who portrays Dr. Alex Karev. "Justin's hilarious. He has a wicked sense of humor."

As far as a romantic connection with Alex goes, Taylor says she has no idea ... mostly: "I don't know. There's no steam yet, I don't think. Depends what you call steam."

Regardless, it's been a great experience so far.

"I wasn't sure what to expect from the cast, but they couldn't be more gracious or welcoming," she reports. "Ellen Pompeo is like the sweetest woman in the world."

"She's so delightful. Patrick is a gentleman. They've all been wonderful."

"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. I didn't expect it."
