NSW teenager Ellie Drennan has won the fourth season of reality talent series The Voice Australia, becoming the youngest person to do so.

Drennan wowed the coaches with a performance of Sinead O'Connor's Nothing Compares To You during the two-hour finale, as well as a stirring rendition of Beyonce's Halo with mentor Jessie J.
"I'm over the moon right now," Drennan said after winning the finale.
"Thank you everyone who voted for me and thank you so much Jessie for always being there for me."
The Price Tag singer and the teenager became close during the competition, with Drennan referring to Jessie J as her "older sister" in the finale.
Drennan also regularly posted photographs of herself and her coach on Instagram.
