Salma Hayek

Angelina Jolie's got nothing on Salma Hayek.

Hayek, current 30 Rock guest star and voluptuous UNICEF ambassador, is creating all sorts of buzz with a video showing her breast-feeding another woman's baby during a humanitarian mission to Sierra Leone to raise awareness about maternal neonatal tetanus. In the clip shot for Nightline last October, Hayek, who gave birth to daughter Valentina on Sep. 21, 2007, takes a malnourished baby into her arms and casually begins to feed him.

The child's mother was also malnourished and was unable to feed her baby. Hayek was still lactating at the time and didn't think twice about helping the hungry child. "That was amazing," Hayek says in the video. "I was able to feed an ill baby that was very hungry."

Hayek jokes that her daughter might be jealous, but then suggests that giving and sharing is a lesson she hopes to impart to her little one. "I actually think that my baby would be very proud to be able to share her milk," Hayek says. "When she grows up, I'm going to make sure that she continues to be a generous, caring person, and I think that's the best thing I can give her as a mother."
