It was a win for Brynn as Longmeadow teenager Brynn Cartelli was crowned the Season 14 champion on NBC’s popular singing competition “The Voice” Tuesday night.

In recent weeks, Cartelli has gone from being a typical 15-year-old to charting on iTunes, gaining thousands of fans across the country and being tutored by pop star Kelly Clarkson.

Clarkson, who has a teenage daughter, said she wanted Cartelli to be happy as well as successful in her career.

She noted t were people already lining up who want to work with Cartelli.

Cartelli, the youngest finalist in the show’s history, got high marks from critics for her three performances on Monday night, especially her powerful, show-closing rendition of Adele’s “Skyfall.”

Cartelli’s rise to TV stardom is amazing for a teenager who was best known until recently for occasional performances at Uno’s Courtyard in Springfield or Cisco Brewery in Nantucket.

Her appearance on “The Voice” grew out of a meeting 15 months ago when producers invited Cartelli to New York after seeing her perform in a YouTube video shot in Nantucket.

Some 700 friends and fans of the teenage singer turned out to cheer Cartelli on as she won “The Voice.”
