Elizabeth Edwards to Nate Berkus: 'I may never know what really happened...'

Elizabeth Edwards granted a rare interview to new talk show host and designer, Nate Berkus

"I had the best time," Berkus tells Zap2it. "We sat for hours talking. We did cover a lot of stuff. She was very, very honest with me, very open. I was in her home."

On the Friday, Sept. 17 episode of "The Nate Berkus Show," Edwards talks about how she reclaimed her life after her son, Wade, died, she was diagnosed with terminal cancer, and discovered her husband had a child with his mistress.

"I think natural resilience (is something) we all have," says Edwards. "Some of it, I learned after Wade died. That was my really long period of having to readjust to a new reality. Then you incorporate the person who was with you still into your life in a positive way, and manage to live happily and laugh again when you thought you never would."
