Christina Applegate underwent a bilateral mastectomy in 2008 to fight breast cancer (she's since been cancer free) and now, life has taken a certain turn for the better, as she welcomed her first child, daughter Sadie Grace, into the world Jan. 27.
"I felt my heart literally open up for the first time and like wrap itself around her. It was profound," Applegate told People magazine. "And I'm more in love with her every minute of the day."
Applegate, fiance Martyn LeNoble and Sadie are all home together in Los Angeles, where Applegate says she is relishing motherhood. "I want to be the ultimate burper and diaper-changer, I want to be the ultimate at all of it," she told the magazine. "Yeah, now I'm Mom. She's healed me in so many ways," says the actress. "She's just made my life so much better. She's opened my whole soul."
