Feeding six kids isn't easy.

Ask Angelina Jolie.

"The problem with my packed lunches is everybody is very, very outspoken about what they want, so it becomes – I often say, 'I'm not a waitress!' " the Oscar-winning actress, 35, said on British morning chat fest GMTV earlier this week. "We go through so much food."

As the kids (now between the ages of 9 and 2) get older, she doesn't expect it to get any easier.

"They're still little," she said, "so I can imagine it's going to get worse."

Still, she doesn't mind.

Jolie, who's currently promoting Salt in Europe, called her children "lovely little people" who provide a "beautiful chaos" to her life with longtime beau Brad Pitt.

"We have a pretty great relationship," she said when asked how they work as a couple. "If anything, we only go through periods where we're working too much and we say, 'Honey, one of us is working too much,' or we haven't spent enough special time.

"As soon as we identify it, we just know we have to find some special time and then we reconnect," she added. "We're never far apart. We raise the kids together. We take turns working. So, we try to stay pretty close."
