Angelina Jolie wants kids to know that it's OK to be different.

The 39-year-old actress made her first post-surgery appearance at the Nickelodeon's 28th Annual Kids' Choice Awards with her kids Zahara and Shiloh, where she picked up the award for Favorite Villain for her work "Maleficent" and reminded her fans that being "different is good."

During her speech, the actress said she was once told she was "different" like her character in "Maleficent" and felt out of place, but added that its fine to be "too loud, too full of fire, never good at sitting still.

"Different is good. So, don't fit in. Don't sit still. Don't ever try to do less than you are. When somebody tells you [that] you're different, smile and hold your head up high and be proud. And as your villain, I would also say - cause a little trouble. It's good for you."

In an article for The New York Times, Jolie revealed that she underwent additional surgery to have her ovaries and fallopian tubes removed in hopes of reducing her risk of cancer. Brad Pitt's wife revealed that she carries a gene that gave her a 50 percent risk of developing ovarian cancer.

"I went through what I imagine thousands of other women have felt," she wrote. "I told myself to stay calm, to be strong, and that I had no reason to think I wouldn't live to see my children grow up and to meet my grandchildren."

Two years ago, the Academy Award-winning actress opened up about carrying the defective breast cancer gene that placed her at high risk of developing breast and ovarian cancer. Jolie's mother died from ovarian cancer and Jolie's maternal grandmother also had ovarian cancer.
