Selena Gomez stops in for a frozen yogurt treat at Menchie’s in Los Angeles on Wednesday.

The 16-year-old Wizards of Waverly Place star was recently named spokesperson for the 2008 Trick-or-Treat for UNICEF campaign, which encourages children to make Halloween count by helping other children around the world.

“I am extremely excited to be this year’s Trick-or-Treat for UNICEF spokesperson,” said Selena. “I want to help encourage other kids to make a difference in the world and show them that Trick-or-Treat for UNICEF is such a great, fun way to get involved.”

“We are thrilled to have Selena be a part of the Trick-or-Treat for UNICEF program this year,” said Caryl Stern, President and CEO of the U.S. Fund for UNICEF. “Young people can relate to Selena, and she is a great role model who we believe will greatly enhance the visibility of the program.”
