She may be a supermodel but that doesn't mean she hasn't struggled in her personal life.

Tyra Banks has just opened up to People magazine about her failed IVF treatments, which she has called "traumatic."

The 41-year-old has been trying to start a family with her boyfriend Erik Asla, 50-year-old Norwegian photographer, but has been unable to -- despite several attempts.

Tyra said she kept putting off kids for her career, "The one thing that I was not happy about in my life was that I did not have kids. Since I was 24, I used to say every year, "I will have kids in three years."'

The superstar added, "My business is very entrepreneurial and I kept trying to find time for it to happen."

But unfortunately now that she's ready to have them -- she's finding the process more difficult. The America's Next Top Model admitted, "Then when you're like, "I'm just going to do it," it's not so easy."

But the catwalk queen isn't letting the disappointment get her down. She told the mag she's still hopeful that she will have a brood. "I don't just want one child. I'd love a litter. Maybe they'll be running the family business. I do want a legacy."

Aww -- we wish the couple the best of luck moving forward. We think Miss Tyra would make a fierce mama!
