There's some VERY tough competition happening. Natalie Portman, Jessica Biel, Leo DiCaprio, Matt Damon and Salma Hayek are all up for awards. Both Matt and Leo are doing their part to bring attention to the clean water crisis, same with Jessica who climbed Mt. Kilimanjaro to raise awareness about Africa's water situation, Natalie hosted a charity event for the film "Hungry in America," and Salma went above and beyond when she visited Sierra Leone health clinics and breast fed a hungry baby who's mother could not produce milk.

What do Lady Gaga and Pete Wentz have in common? Not much... except that they're both up for a Do Something Award for their work this year. Gaga donated proceeds from one of her concerts to the Haiti relief fund and also raised awareness about AIDS worldwide. Pete was named the spokesman for UNICEF Tap, an organization dedicated to providing clean drinking water to children everywhere. Other musicians up for the prize are Shakira, Christina Aguilera and all three JoBros.

Who says u can't care about how u look and about helping people? Several high-profile fashionistas know how to balance both worlds.

Nigel's powerful foto exhibit titled Haiti: Hunger and Hope is the perfect example of how to use whatever talent u have to make a difference.
