​Julianna Margulies on playing "The Good Wife"

"Well, he was sort of hitting on me in a way," she said. "And I was charmed. But I just assumed he was an actor. We met through a mutual friend who was an agent. And it was a whole bunch of theater actors at this dinner."

"But he said, 'No, I'm actually a lawyer.' I was so stunned. And he said, 'Well, I was a Wall Street litigator for six years, but I just recently quit. I didn't like who I was becoming.' And I thought, 'Oh my God, I like this man. He's a thinking, feeling, smart human being.'"

He proposed in Paris. And she said yes.

"We came home, and six days later I found out I was pregnant," Margulies said. "Which, you know, at 40 was not just shocking but miraculous. So I said, 'Well, we'll wait until the baby's born and then we'll get married.' And Keith just said, 'No, I want to get married with you pregnant.' And I said, 'Great.'

A year after the birth of their son, Kieran, CBS offered her a starring role in "The Good Wife." Season 7 finds Alicia Florrick restarting her legal career.

Pauley asked, "What's your IQ?"

"I don't know," she laughed.

Shot on a Brooklyn soundstage, the show's proximity to Broadway has attracted theater veterans like Christine Baranski and Alan Cumming, who plays political operative Eli Gold.

"I came into it about two-thirds of the way through the first season," Cumming told Pauley. "All I knew about it was that it was about Jules and I knew it would be -- you know, she's got quality in her veins."

Quality that has been recognized with two more Emmy Awards for Best Actress -- in 2011 and last year.

And at 49, Julianna Margulies says she has much for which to be grateful. "There's a different appreciation you get for things when you're at a different time in your life. And I obviously waited for the right time, and I got lucky, I got so lucky. I mean, I pretty much say it every night when I go to bed, how lucky I am, and with everything. I love my job. "
