The 33-year-old actress made the big announcement on Monday’s Oprah Winfrey Show. So far, Drew has taken two trips to Kenya to see the WFP’s work first hand.

“I have seen with my own eyes what a difference a simple cup of nutritious porridge can make in a child’s life,” Drew said. “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.”
