Now, heidi is speaking out to katie couric about her high-profile split from seal. And what's really going on with the family bodyguard. Take a look. Heidi klum did not hold back. I don't know if we're like the greatest friends right now, especially the things he said. Reporter: In her first television interview on "katie," the supermodel turned supermogul talks about a rollercoaster of emotion and shocking headlines, since her split from seal eight months ago. Talk about how you're doing right now. It's very hard. Especially being in all of the magazine and gossip pages. That's hard and hurtful. It's hard to go through a divorce, you know, if you're not in the public eye. Or if you're in the public eye, it's horrible. Reporter: The once-loving couple was famous for renewing their vows every year. But those public moments hid deeper problems. People saw it laughing and smiling. But it's not always like that. When you have a bad day, you don't say that all the time. You just deal with it and move on. Reporter: And at first, that's what the couple seemed to be doing. In what appeared to be an Still, in my opinion, the most wonderful woman in the world. Reporter: But soon, public civility turned ugly. Two weeks ago, the soulful singer delivered a low blow, when he responded to rumors that heidi was romantically involved with the bodyguard for four years. I would prefer that heidi had more class, and waited until we separated before deciding to fornicate with the help. That's a unique choice of words. I'm used to them. Reporter: Klum talked openly with couric about the accusations. I was never with another man when I was with him. Reporter: And today about the bodyguard, martin kirsten. We got to know each other from a completely different side. He's been with our family far the last four years. He cared for our entire family. Mostly for our four children. Helped us tremendously. You are in a relationship right now? I don't even know if I can call it that. I don't know. It just started. So, I don't know. We wish both of them the best.
