So when he set out to interview Banks, the talks were spread out over three weeks, giving him a good peek inside the world of the woman who hosts a daytime talk show, models and is the producer and host of "America's Next Top Model."
"You can't learn as much if you just sit with them in one setting," he said of the series of specials his company produces for E! "It was interesting, from my perspective, to see how she executes her day."
Banks' day, he learned, always includes a 6 p.m. break for dinner. At times, Banks talks about how hard it is to find a man in her life.
"I don't have a boyfriend....I'm still waiting for them to call me back," Banks told Seacrest. "They don't know I'm looking at the phone all day going, 'You gonna call me?'"She also admitted some editions of her daytime show made her cringe, and discusses when she had her breasts examined on-air.
"After the [breast] show, I went home and cried. I felt really vulnerable," Banks said. "I was like, 'Did I do the right thing?'"
Seacrest said viewers will get a chance to see the person behind the Banks people see on TV. "I really think the idea was, for her and me," he said, "to roll up our sleeves and show her life in an unvarnished way."
