Selena is an ambassador for Unicef for the second year. Unicef is a group that helps support unfortunate children in different countries, but mainly Africa. All you need to do is when you go around Trick-or-Treating, say to the homeowner that you are supporting Unicef. After Halloween night is over, send the money to Unicef. Visit youth.unicefusa.org/trickortreat/ for more information. Selena will also be doing a live webcast on October 29th on Facebook.
