Tyra Banks has revealed that she doesn't want to "slow down" her life and become a mother.

The 40-year-old model, who fronts America's Next Top Model and has her own talk show, is proud of being an "overachiever".

"I don't want to slow down and stop. I think there's a weird thing with women when we're high achievers and have high goals, sometimes it's like, 'Why don't you just sit down and have a baby?'," she told Metro.

"I know I'm an overachiever and I'm not apologetic about it. I won't be slowing down any time soon; it's only going to get bigger."

Tyra, who is the new face of Special K cereal, admitted she decided to speak out when she received negative feedback about her figure.

"Body image is something that has been important to me for a long time. So when people were saying I was fat, gross and disgusting, they weren't just saying it about me, they were saying it about any woman whose body looked like mine." she said.

"I felt I needed to say something so I was very vocal and told the people who had negative things to say about me - or women that looked like me - to kiss my fat a**."
