VIDEO: Christina Applegate: Being A Mom 'The Best Thing That's Ever Happened To Me'

Christina Applegate, speaking publicly for the first time since having her baby daughter Sadie Grace LeNoble three weeks ago, describes the "profound” pains of giving birth on The Ellen DeGeneres Show Tuesday, and says that parenthood’s “best thing that's ever happened” to her.

Applegate, a breast cancer survivor, said that her January 27 labor took "about 18 hours" in total.

"I had my plan," the 39-year-old Married... With Children star said. "Plans are a big joke, you know, mine was to have an epidural, but I didn't react to it well... I didn't like it.

"I didn't like the feeling of numbness. I didn't like it. It was really creepy to me. It was too much so we turned it off and we opted for go all the way."

"Wow!" DeGeneres said. "How was that?"

"I like to say that I opted for it, but they accidentally turned it off," Applegate said.

As for the pain?

"It was profound -- it was profound pain, and then that happens," Applegate said, before showing off a photo of her adorable little girl.

"Just that moment, pulling her out and I dropped my gown which I don't do," Applegate said. "This part of my body is very private to me her chest ... that's a real private place. A place that I don't have a good relationship with, let's say.

"But at that moment of pulling her out and I just tore that thing gown off,” she continued. “There's a room full of people that I don't know. Nurses and doctors. And she and I just laid there.
