Niki Taylor: Life in the fast lane left this supermodel divorced with twins at the age of 21, amid a few other personal struggles.

Now with her NASCAR- driver husband, 1-year-old baby girl, and two teenage boys, Niki’s loving life  at a much slower pace.

What’s it like to have teenagers and a baby?

Everybody gets along wonderfully, and the boys [Jake and Hunter] are great with Ciel [SEE-el]. She just digs ’em. She always says, “Oh, there’s my brudders!” We’ve been talking about having another baby. It would be nice to give her a little brother or sister pretty soon. Plus I’m not a spring chicken anymore.

What were the benefits of having kids when you were so young?

I had them at 19, but I knew when I was 16 that I wanted to have kids early. I had more energy then. I never really thought about having to run after two of ’em and having to change double diapers. I feel bad for people who are my age having twins. It’s a lot of work!
