Christina Aguilera leads team into The Voice singing battle

Curvy Aguilera wowed the audience in a revealing blue dress as she belted out Lady Marmalade with the four remaining contestants on her team in the hit singing show.

In the first quarter final - and live event of the season - Aguilera put her singers up against those of country singer Blake Shelton, with each coach losing two singers by next week.

The show kicked off with all four of the coaches, Aguilera, Shelton, Adam Levine and Cee Lo Green, combining forces to perform a medley of hits by British rock legends Queen.

The best performance of the night came from Team Blake's Dia Frampton who sat at a piano to perform Kanye West's Heartless, which drew massive praise from all of the coaches.

Team Blake's Jared Blake performed Use Somebody by rockers The Kings of Leon, while young Xenia Martinez took on Price Tag by British pop star Jessie J.

The final Team Blake performer, country singer Patrick Thomas, covered the ballad I Hope You Dance by Lee Ann Womack.

Shelton also led his team in a rendition of This Love by Adam Levine's band Maroon 5.

For Team Aguilera Raquel Castro kicked off performing Ke$ha's Blow, while shaven-headed Beverly McLellan belted out I'm the Only One by Melissa Etheridge.

Pop singer Lily Elise then covered Fergie's song Big Girls Don't Cry, while former American Idol contestant Frenchie Davis did When Love Took Over by David Guetta.
