Charlize Theron fights back the tears on Oprah

Caring Charlize Theron fought back tears as she told how she is helping save lives in her native South Africa.

The Hollywood beauty is working with chatshow host Oprah Winfrey to provide a mobile health clinic and education centre to tackle the devastating threat of HIV and AIDS.

She struggled to contain her emotions when she appeared on Oprah’s show to talk about the project and watch a video of her recent visit to Africa.

The clinic travels to four schools in remote and impoverished areas of KwaZulu-Natal to give HIV tests and vital sex education to students.

Charlize told Oprah: “It’s where I’m from. It’s in my bones and it’s in my blood.

“When I go there and I see those kids and I’m around those people, I know that’s where I belong.

“I think that’s the thing that gets me because I’ve been so incredibly blessed in my life.

“My life could have turned out very differently.

“I could have been there, physically living the struggle with them.

“Those kids have a 50% chance of contracting HIV and AIDS and dying from it, and that could have been my life.”

Charlize, who partners Oprah’s ‘Angel Network’ in the project, is auctioning off the dress she wore for her first Cannes Film Festival on eBay to help raise funds.

The one-off dress is between a size 6 and an 8 and was shown off by a model, but Charlize insisted women don’t need to be stick-thin to wear it.

She said: “There’s a lot of give in it.

“I’m not a small girl. I’ve got meat on these bones. I’ve got junk in my trunk.”
