Jessie J has hailed Usher's iTunes Festival 2012 performance as "incredible", after enjoying a night off from working on her new album to watch the R&B star in concert.

The 'Domino' star described 'Scream' singer Usher as "perfect" for his show at the Roundhouse in Camden, London, and reveals she even got to dine out with him after the show.

"Night off :) Usher was perfect. WOW *heart eyes*," Jessie tweeted last night (1st September), before adding: "Gym- Studio - @UsherRaymondIV show at Roundhouse *INCREDIBLE* studio to finish vocals - dinner with @UsherRaymondIV and his team. #greatdaynight."

Usher helped launch this year's iTunes Festival last night with the first performance of the month-long event, which will also see the likes of Jessie J, One Direction and Pink taking to the stage.

The 'Climax' singer performed tracks from across his lengthy music careers including songs from recent hit US album 'Looking 4 Myself'.
