Beverly McClellan, a former South Fork High School student who, in 2011, became a finalist on the first season of "The Voice," died Tuesday, according to her wife, Monique, who posted the news on Facebook. She was 49.

McClellan was diagnosed March 30 with stage 3c endometrial cancer. The cancer metastasized and spread to her bladder, colon and intestines, according to a GoFundMe page set up for the singer/songwriter.

McClellan's raw, soulful sound made her a fan favorite on "The Voice." During the blind auditions, where performers sing to four coaches whose backs are turned, McClellan belted out Janis Joplin's "Piece of My Heart." Coaches Adam Levine and Christina Aguilera turned their chairs for McClellan, who picked Aguilera to be her coach.

Throughout the competition, McClellan sang "Baba O'Reilly," "I'm The Only One" and "The Thrill Is Gone." She also sang "Beautiful," a duet with Aguilera.

Born in Kingsport, Tennessee, McClellan started singing at 24 and had been performing at clubs and bars around Fort Lauderdale for 20 years. She released six albums, all on an independent label. She also won the New York National Music Festival in 2004 as Best Overall Performer. There were 500 contestants.

In 2012, she performed at Pride of the Treasure Coast's PrideFest, just a few months after her appearance on "The Voice."
