Drew Barrymore has donated $1million (£503,000) to the United Nations' World Food Programme (WFP) to help starving children in Kenya.
The actress announced her "incredible donation" on the Monday edition of Oprah Winfrey's chat show, telling Winfrey she was determined to help the WFP's $3 billion (£1.5 billion) Fill the Cup campaign to feed 59 million school children in developing countries.
"I have seen with my own eyes what a difference a simple cup of nutritious porridge can make in a child's life," the Charlie's Angels star explained.
Barrymore, 33, has travelled to Kenya twice in the past two years as part of her work as a WFP ambassador against hunger.
"It helps them learn, stay healthy and sets them on track for a bright future. I urge everyone - everywhere - to help WFP 'Fill the Cup' for hungry children, and make hunger history," she added.
Josette Sheeran, WFP executive director, also on the show, said the agency has "a dream to feed another ten million hungry school children in Africa by Thanksgiving Day".
Twice-divorced Barrymore was also quizzed about her relationship with Die Hard 4 star Justin Long, which she described as "the best".
"This relationship is great; it's healthy and it's productive and it's supportive and it's full of humour," she added.
Long, 29, is starring alongside Scarlett Johansson and Jennifer Aniston in upcoming comedy He's Just Not That Into You, produced by Barrymore's Flower Films.
When asked what he liked about Barrymore, the Accepted actor explained that "she smells good".
"She's beautiful and funny," he added, "The most compassionate person I've ever met."
Barrymore was married to Welsh barman Jeremy Thomas, who she divorced in 1995, before marrying comedian Tom Green, divorcing the Canadian in 2002.
