The Oscar-winning actress, Grammy-winning singer and now fashion designer is also a Smash on TV.

We’re thrilled to see you strutting your stuff on Smash. How’s that been for you?

Veronica Moore is a great character, and being on a great show like Smash is a lot of fun. It feels like a family there, and I’m loving every minute of it.

And you recently launched your own clothing line with QVC.

I absolutely love clothes, and one of my favorite places is my closet! I created a line that represents my style but that everyone can afford. And I want all women—no matter what their size—to look and feel fabulous in the clothes.

You recorded the song “Lullaby and Goodnight” in collaboration with Pampers. How was it re-creating a classic?

People have a certain expectation of how the song sounds. But when you sing it from the heart, it makes it easier. After all, no one can express how much you love your child more than you can. Putting my own words to it makes it special to me, and i sang it as if I were singing to my son, David Jr.

What do you usually sing to him?

If course I sing my lullaby, but he likes nursery rhymes, too. “Where is David? where is David? Here I am, here I am!” that’s his favorite. Around the holidays I sing jazz music, too.

David is 3 now. Is he musically inclined yet?

One night he performed “Proud Mary” because he didn’t want to go to sleep! It was 2 a.m. and there he was with a mike, dancing and singing to the beat. It was very entertaining, but he still needs to work on the lyrics a bit!

How is it parenting in the spotlight?

It can be very overwhelming. that’s why my fiancé David [pro wrestler David Otunga] and I chose to go back home to Chicago. We want our son to grow up around normalness. Being in Chicago balances us.

What’s your idea of the perfect holiday?

Family, family, family. our favorite place is the couch. The best part of the holidays is the cooking. I love turkey wings, greens and baking cookies. I’ll bake them even if no one eats them!

And all that baking makes your house smell delicious with zero calories.

That’s the best part of all!

JENNIFER’S HOLIDAY EATING TIPS

Keep control.
It’s all about the  portions. Thank God for Weight Watchers, because now I know what my portion sizes should be.

Celebrate selectively.
I love holiday food, but I have to remind myself that not every day during the season is a  reason to eat a lot.

Curb your appetite.
The house smells so good during the  holidays, but you should only eat when you’re really hungry. Drinking  a glass of water helps to curb hunger.

Pick one comfort food.
I have a weakness for sweet potato pie, but I can’t overindulge. So I make sure to have a slice and truly enjoy it.
