Perhaps Selena Gomez's recent appointment to ambassador at UNICEF will finally make those trick-or-treat cash collection boxes chic on Halloween.

Gomez, who worked on the 2008 Trick-or-Treat Halloween Campaign for UNICEF, is the youngest ambassador selected by the United States Fund.  The Wizards of Waverly Place actress will leverage her fame and talent to raise money for children's causes abroad and educate others about following the UNICEF mission, to reduce the percent of preventable deaths in children.

About her appointment, the young Latina told the press:

I know we can achieve this because every moment, UNICEF is on the ground providing children with the lifesaving assistance needed to ensure zero [deaths] becomes a reality.

Selena's UNICEF work will sure teach this pretty young thing to take on a more low maintenace routine.  As her first act of duty, Gomez will visit Ghana, one of the countries holding the highest rate of mortality in children under five.  There, the Disney actriz will observe the sordid conditions in which West African children live, and help propose solutions on how to improve their quality of life.

Gomez isn't the only celebrity on the UNICEF roster. The actress-singer joins fellow ambassadors Joel Madden, Lucy Liu, Clay Aiken, Alyssa Milano and Sarah Jessica Parker in the good fight for los niños. [Unicef.org]
