Her relationship with Justin Bieber may have raised the heckles of a few million wishful thinkers, but even her biggest cyberbullies will have to admit that teen idol Selena Gomez just made one young fan pretty happy.

Gomez, along with Ryan Seacrest, helped with the recent launch of the Children's Hospital of Philadelphia's new media center, christened The Voice. The center includes a recording studio, so Gomez joined an adorable young heart patient named Julia for a performance of her single 'Who Says.'
