Angelina's Secret? Brad And Comfy Shoes

(CBS)  Angelina Jolie, pregnant with twins, has some secrets for staying serene at the Cannes Film Festival: get her partner, Brad Pitt, to babysit, and wear comfy shoes on the red carpet.

Jolie was at the festival Thursday to promote DreamWorks' animated "Kung Fu Panda." She'll be busy at Cannes, as she also stars in Clint Eastwood's "Changeling," which is also to be shown.

But the mother of four - soon to be six - swears she's not working too hard.

"I'm sitting and talking a lot, and everybody's being very nice to me," Jolie told reporters. "If I was feeling too pregnant everybody said I didn't have to come."

The 32-year-old actress also confirmed that she's thinking about giving birth in France.

"I actually haven't completely decided, but we are certainly thinking of France," Jolie said. "It's a second language in our house. I'm still learning so I'm not going to attempt it here today, my rusty French. But our children are starting to speak French, so being here is very good for them for their language."

She also revealed a red carpet beauty tip.

"I'm going to do a shoe ad right now - Cole Haan makes a shoe with a Nike sole, so I have a low heel with a Nike sole," she said.

While Jolie was being swarmed by photographers, Pitt was taking care of their children. He was joining her later for the "Kung Fu Panda" premiere.

"He's with our kids right now, but he'll get his suit on at the last minute, I'm sure," she said.

Jolie is the voice of an assertive tigress and martial arts maestro in "Kung Fu Panda," which also features the voices of Jack Black and Dustin Hoffman. The actress says she's not a fierce feline at home.

"I think I have a very even partner right now, and I think we're very balanced at home with our power-sharing," she said. "But I think every woman in some way is a tigress or would like to be."
