In an exclusive conversation with HELLO! after her win, she revealed that her daughter's reaction to the mention was quite unexpected.
"My daughter actually cried," she said. "She was confused about how I spoke to her through the TV. And I was like 'Are you kidding?'"
"So I called her, she was supposed to be in bed to go to school tomorrow. I didn't expect that to be the reaction. But I think in ten years she'll appreciate it," she continued.

The Mean Girls star also mentioned her son, saying: "I don't know about my son, he's too young to know anything, really."
Clearly, the honor meant a lot to the family as she added: "But I really wanted to do that for them, and my husband was like 'You've got to just talk to them when you get up there, you've just got to talk to them. Those are the people that matter and this is what you're doing it for now.'
"I don't know, I've gotta have a conversation with her when I get home."
In her acceptance speech, Amanda sweetly told her daughter: "Hi! Bubs, you gotta go to bed now, but thanks!" while also adding a message of gratitude to her loved ones.
