"We've been rubbing it for good luck!" she exclaimed to ET's Carly Steel on the carpet. "Rub the belly for good luck."

She also joked that she chose her look based on comfort. "I picked it based on stretchy-ness," she dished. "Long story short."

As for revealing the gender of her baby? The English actress played coy, telling ET, "I'm not telling yet, [but] I might actually reveal it the end of this week!"

The blond beauty announced she was pregnant via Instagram last October with an adorable pic of herself holding a pumpkin with gold lettering that read, "Baby arriving spring 2017."

When ET caught up with Luddington earlier this month at Disney/ABC’s Television Critics Association all-star cocktail party, she couldn't stop gushing over the parenting advice she's received from her Grey's co-stars, Ellen Pompeo and Caterina Scorsone.
