Ariana Grande has hit No.1 on iTunes in nearly eighty countries worldwide.

The singer unleashed her second album 'My Everything' on Monday (August 25) and it has been going down a storm.

She has reached the summit of 78 countries' iTunes charts, including in the US and Brazil.

However, Royal Blood's self-titled debut has blocked Grande from topping the iTunes chart in the UK.

The album features the singles 'Break Free' and 'Problem' and it marks the follow-up to her 2013 debut 'Yours Truly'.

Grande performed the former track at the MTV VMAs on Sunday (August 24).

She also lined up alongside Nicki Minaj and Jessie J for their collaboration 'Bang Bang'.
