Selena Gomez Rocks Gently For a Good Cause (VIDEO)

Justin Bieber’s not the only one who’s breaking it down acoustic-style these days. Bieber’s pal, Selena Gomez, stripped things down to the basics at the 450-capacity Roxy Theatre in West Hollywood on Tuesday night, treating the select crowd to an intimate concert to commemorate the 60th anniversary of UNICEF’s Trick-or-Treat program, which annually raises funds for disadvantaged children worldwide. (Gomez, 18, serves as an ambassador for UNICEF.)

The Wizards of Waverly Place star and her band, The Scene, wowed the audience with acoustic versions of their songs “Intuition,” “Magic” (a cover of the classic ’70s song by Pilot) and other songs. The Scene was joined by special guests Allstar Weekend and YouTube singing sensation Christina Grimmie for the concert.

Gomez’s good deeds for the night didn’t end with her promotion for UNICEF. During her performance of “A Year Without Rain,” the singer/actress brought a lucky (and adorable) young fan on stage to duet with her. Check out SelGo’s fan collaboration below.
