Yep, you got the second part right. She has said many times on the show that her day begins at 6am every day. She takes care of Mark and the kids, then heads to work by 8 and works till 11, unless she is on location where the day quickly becomes much longer.
She is a good mom, and a good wife, is fun, lighthearted, and caring. I say good for her, it won’t last forever, and I wish her happiness.
She works a couple of hours a day then hits the gym.
