LOS ANGELES — Melanie Amaro has “The X Factor.”

The powerful 19-year-old vocalist from Sunrise, Fla., won the Fox talent competition last Thursday over soulful 30-year-old singer Josh Krajcik of Wooster, Ohio.

Amaro, who was mentored by judge Simon Cowell and was at one point eliminated then reinstated to the contest, was awarded the grand prize: a $5 million recording contract and a starring role in a Pepsi commercial.

“Oh my God. Oh my God. Oh my God,” Amaro repeated after host Steve Jones announced her as the champion.

Despite continued prodding from Jones, an overly emotional Amaro couldn’t quite formulate words when she was revealed to have captured the most viewer votes, and she struggled through tears to reprise Beyonce’s “Listen,” the soaring ballad that Amaro crooned at her audition and on Wednesday’s final performance round.
