Witherspoon, 35, filed for divorce from Ryan Phillippe in 2006. She calls the break up "really traumatic" and worried about the effect it would have on their two children, Ava, 12 this month, and Deacon, 7½.
"I was hard on myself when I got divorced. And until I got remarried, I don't think I realized how stressed I was," Witherspoon says in the October issue of Marie Claire. "I don't think I recognized how anxious I was about being a single parent."

The Oscar-winner was also concerned about finding a man who would accept her kids, but says all that changed when she met agent Jim Toth, whom she married in March.
"Now I feel a great sense of relief and an incredible amount of support from my husband," Witherspoon says. "I got very lucky, and he's wonderful. And so wonderful with my children. I'm very blessed."
