But the actress's curly locks just aren't good enough for her character on "The Good Wife." And it cost the show's producers a pretty penny to do something about it. (Video via CBS / "The Good Wife") "That's a wig," said Julianna Margulies on the "Late Show." "No, it's not," said David Letterman. "Isn't that a good wig?" said Julianna. "That's fantastic," said Dave. "Yeah," said Julianna. "Ten grand. That wig cost ten grand," said Dave. "Ten grand," said Julianna. "Whoa! Whoa!" said Dave. You heard right — Julianna wears a whopping $10,000 on her pretty little head for every episode. She told David Letterman it's so valuable because it's made of real hair, and it was created to match her exact hairline and everything. But Julianna doesn't mind wigging out for "The Good Wife" at all. In fact, she told Sundance TV she prefers it because it saves her a lot of precious time. "I wanted her to have a little bit of that WASPy look to her and I'm a Jew with curly hair, and I know that that takes two hours every morning in the makeup chair."

New episodes of "The Good Wife" premiere March 1 on CBS, and the show was recently renewed for yet another season.
