Jessie J has had a BIG week.

The 24 year old singer just wrapped up her time on The Voice on Saturday night, as the series ended with the triumph of powerhouse vocalist Leanne Mitchell. Her act Vince Kidd may have come last but she enjoyed a moment in the spotlight herself, when she took to the stage to perform a duet with the London born hopeful.

This evening, Jessie returned to what she does best and gave a live performance at the Queen’s Diamond Jubilee concert in London.

The event was staged outside Buckingham Palace for a crowd of 18,000 people and Jess performed her hit single ‘Domino’ to a rapturous audience.

She looked stunning in a floor length gown, with a thigh high and very revealing split and after showcasing a shoulder length haircut at the weekend, this evening her extensions were back and her hair was scraped into a high ponytail.

Jessie also performed at the concert with her fellow Voice coach will.i.am and the pair collaborated on the hit Black Eyed Peas song ‘I Gotta Feeling’.

The pair are becoming old hands at this, having taken to the stage for a mash up of some of their and Tom Jones, Danny O’Donoghue’s greatest hits on Saturday.

Check out the duet below…Did you enjoy it?
