Back from her recent trip to Ghana, Selena Gomez is at it again. The Disney star, already UNICEF’s youngest ambassador, will be the spokesperson for their Trick-or-Treat campaign this year. Selena was the spokesperson last year too! The campaign encourages kids to make a difference on Halloween by carrying those famous orange boxes to collect money as they trick-or-treat. Over the 58 years of the program, UNICEF has collected $140 million. The money helps bring water, education, and medicine to children in need around the world.

Check out the YouTube video Selena posted, urging kids to join the campaign and raise money for UNICEF.
