(Cover) - EN Showbiz - Angelina Jolie is just a "regular mom" who dotes on her children.

The Oscar winning actress took some of her brood to a petting zoo just outside of London recently where onlookers were amazed by her down-to-earth nature.

An eyewitness told Life & Style that Zahara, seven, and three-year-old twins Knox and Vivienne were so "well-behaved and really polite."

"She put the kids' shoes on, watched them run down the slides and bought them snacks from the caf," the bystander told the publication. "She was a regular mom."

"Most of the other moms were pretending like there wasn't some bercool famous actress in our midst.

"She's really amazing. She said hello [to me] in a very movie-star kind of voice."

Angelina and partner Brad Pitt recently announced their engagement although they have not revealed any immediate plans to tie the knot. They have three other children; Maddox, Pax and Shiloh. (C) Cover Media
