The 42-year-old actress—who gave birth to a daughter, Valentina Paloma, in November 2007—was on a charity mission at a hospital in Sierra Leone last week when she encountered an impoverished woman who's incapable of feeding her baby boy. Wasting no time, Salma sprang into action and took matters into her own hands.With a camera crew from ABC's Nightline rolling film, Hayek brought the hungry child to her breast and began nursing him.

"The baby was perfectly healthy, but the mother did not have any milk," Hayek noted later. "He was very hungry—I was weaning my daughter Valentina, but I still had a lot of milk, so I breast-fed the baby." The From Dusk Till Dawn beauty added. "It was amazing because he's really looking at me and he's very little. My baby is one year so she can suck a lot harder."

Hayek did, however, admit to conflicted feelings about her charitable act: "I thought about it; am I being disloyal to my child by giving my milk away? I actually think my baby would be very proud to be able to share her milk and when she grows up I will make sure she continues to share and be generous caring person."

Way to work toward a better future, Salma.
