Los Angeles, CA -- New mom Reese Witherspoon is being honored by March of Dimes for being a model celebrity parent.
The 36-year-old Oscar winner and mother of three will receive the organization's Grace Kelly Award at its Celebration of Babies luncheon Friday at the Beverly Hills Hotel.
Witherspoon gave birth in September to a son, Tennessee, with her husband, talent agent Jim Toth. She's also mom to Ava, 13, and Deacon, 8, from her previous marriage to actor Ryan Phillippe.
Witherspoon says she was "very lucky to have a healthy delivery and leave the hospital with a healthy full term infant, but so many families in this country do not get that experience."
She hopes her involvement with March of Dimes calls attention to its efforts to prevent birth defects and premature birth.
