Scooter Braun has revealed his pride at seeing Ariana Grande dominate the US iTunes chart.

The young singer recently released her Iggy Azalea collaboration 'Problem' and it instantly shot to No.1 on the digital downloads list.

However, it is still at the top of the US iTunes chart - something that pleases manager Braun.

He tweeted: "Damn proud seeing @ArianaGrande still at #1 on itunes with her single #Problem!"

Braun later added: "Currently The #1 Song in the World :) @arianagrande #Problem."

'Problem' meanwhile is due to feature on Grande's upcoming second album, which is expected to land later this year.
