In the first episode of the series, Chapman tried a master cleanse, but Schilling, 30, is adamantly against such a dramatic diet.
"I will never do that," she tells PEOPLE. "I like chicken. And beans."
With only a few weeks until the Emmy Awards, the nominee for lead actress in a comedy has chosen her date (manager Molly Madden) and must-bring snack (almonds) for the evening. The one thing she hasn't decided on is her gown.
"Here's the thing," she says. "I never feel like I'm in the cool kids club with clothes, so I just put on what I like."
One color she won't be wearing? "Orange," she says, laughing, "Someone would have the right to throw eggs at me if I wore orange."
If she wins, Schilling says, "I’m pretty clear on what I'd want to say if I’m fortunate." But she absolutely won't pull out any index cards from her cleavage. "Prepping a speech at all sounds like bad juju to me," she explains.
The 66th Primetime Emmy Awards air on Aug. 25 (8 p.m. ET) on NBC.
