Camila Alves Gushes Over Her Kids, Reveals Family Christmas Traditions

Find out what Matthew McConaughey's wife told us about being a mom of three

Camila Alves and Matthew McConaughey are getting ready for the holidays.

And that means helping their kids Levi, 5, and daughter, Vida, who will be three in January, write letters to Santa Claus.

"It was so cute because Levi was so specific about everything," Alves said yesterday when she stopped by E! to shoot an appearance for tonight's Fashion Police (airing at 9/8C). "One of the things he needed to put was the size. He was like, 'We need to tell Santa Claus the size because he's not going to know the right size.'"

Alves recently took Vida to buy toys for less fortunate kids. "She was so sweet," Alves said. "She's over there picking going, 'A little girl would really like this and a little boy would like that.' She couldn't wait to get home and show everybody. She laid them all out in the garage and she sorted them by boys and girls."

The holidays will also mark baby Livingston's one-year birthday on Dec. 28.

"We try to lead a very simple life as much as we can in the aspect of how big our life is," Alves said. "So we're hands on, we're very, very hands on. Tonight's my third night with no sleep because the kids have been sick."

And this also means Alves doesn't worry about getting dolled up every day, even though the paparazzi may snap an unflattering shot or two.

"You know what," Alves said. "I used to be a little concerned about that before, but I'm not now. I think the only time that I worry about looking good is on the red carpet."

With McConaughey an awards season favorite for his work in Dallas Buyers Club and Mud, expect to see a lot of Alves on the carpet in the next few months.

And on buses and billboards. Her friends have been sending her photos they've taken of her outdoor ads for Macy's I.N.C. International Concepts. Alves was named the face of the brand in July 2012.

"I like to be very conscious every time I do a partnership with anybody. I don't like to do things for money or anything like that," she said. "What I love about this brand is that they have all kinds of things. My favorite thing about the brand is that they include every type of woman, from petite to plus size. It doesn't matter what sense of fashion you have, you're going to find something in the brand. Every woman should be able to find something. And it's kind of my philosophy on everything that I do, I want to include all women. And it's very affordable, the quality is great, and they're very fashion-forward. It was a good match."
