The sound was like 10 squadrons of seagulls about to dive-bomb a July 4 picnic. Ranging in age from 7 to 37, a few thousand females and a handful of males thronged the King of Prussia Mall where Selena Gomez, pop singer and star of the movie "Monte Carlo" made an appearance.

"She's awesome!" said Olivia Monahon, 9, who attends Woodstown Middle School in New Jersey.

"She inspires me to be a better person!" chimed in Mary Mcelhone, 16, of Upper Darby.

Sarah Freymoyer, a mom from Chester County, thus explained the appeal of the petite teen powerhouse: "Her songs are about empowerment and positive messages."

Viva Selena!
