Her hugely-anticipated second album My Everything debuted at Number One on the Billboard 200 chart last week.
And Ariana Grande’s latest slice of pop perfection, which boasts collaborations with the likes of Iggy Azelea, Big Sean and Childish Gambino, also features the handiwork of One Direction heartthrob Harry Styles, who wrote ballad A Little Bit Of Your Heart specifically for her vocals.
Harry, 20, decided to explore the theme of being in an open relationship and had help coming up with the arrangement from songwriter Johan Carlsson – and Ariana was blown away by the results.

She explained to heat magazine: ‘I was very touched. It’s about loving somebody so much that you’re willing to share them with somebody else and being OK with that.’
The 21-year-old singer was nervous when she heard the teen idol had recorded a demo for her so she could learn the song in her own time.
Quizzed by the magazine whether she felt pressured working with someone so famous, Ariana replied: ‘No, I was more intimidated, because he recorded a demo for me so I could learn the song.

‘I was like “I don’t know if I want to make it my own”.’
The starlet has no doubts Harry is a talented songwriter in his own right and believes there are big things ahead for the Midnight Memories singer.
‘Absolutely… His writing to me is just as good’, she insisted when questioned whether his lyrics lived up to his gravelly voice.

Since the news of the collaboration broke last month, speculation has been rife about the nature of Harry and Ariana’s relationship.
The former Disney star, who previously dated The Wanted’s Nathan Sykes, put an end to the rumours during a recent interview with Nova FM.
‘Hes’ just a nice friend,’ she said.
