Heidi Klum has admitted she is dating her bodyguard.

The 39-year-old model - who split from estranged husband Seal earlier this year - confirmed she has been seeing Martin Kirsten, but insists she ''doesn't know'' where their relationship will go because it's still in the early stages.

Speaking on Katie Couric's show 'Katie', the German beauty - who was accused by Seal of cheating on him with Martin before he then claimed his quotes were taken out of context - said: ''I don't even know if I could call it [a relationship], you know, it has just started. I don't know, I don't know where it is going to go.''

Heidi admits she trusts Martin with her children - Leni, eight, Henry, six, Johan five and two-year-old Lou, who she raises with Seal - after knowing him for four years, and insists she is just trying to do what is best for her kids at the moment.

She added: ''I've known him for four years and he's been with our family for four years. He's cared for our entire family, mostly for our four children. He's helped us tremendously, he's helped our children. I trust him with my children. We just got to know each other from a completely different side. I'm trying to think of my kids right now, I'm trying to protect them from all of this. I'm taking it one day at a time.''
