Ariana Grande graces the cover of the September 2014 issue of Seventeen magazine (out August 5!) in which she opens up about her fans, collaborating with Iggy Azalea, her grandfather’s advice and the most difficult thing she has ever dealt with.

Ariana is just as dedicated to her Arianators as they are to her, even going so far to purchase one of her old songs that didn’t make it on her first CD in order to please the fans.

“If my fans want something, I’ll always do my best to give it to them,” she revealed. “A lot of my fans are in love with my old music, and they’re always asking me if they can have the songs that didn’t make it on the first album. I had to buy ["Boyfriend Material"], so I could just give it to them for free. I really wanted them to have it because they love it!”

But of course, Ari is also enjoying the success of her new hit, ‘Problem,’ telling the magazine about why collaborating with Iggy Azalea gave the song that extra edge:

“For me, a collaboration is taking a song that is great, and turning it into a fantastic song,” she explained. “When you hear Iggy [in 'Problem'], it screams confidence and girl power, and all these wonderful things.”

Ariana also discussed some more difficult moments in her life, like the hardest thing she has ever had to deal with — which was losing touch with her father.

“It’s private, but it happened last year. It took me so long to be okay with it,” she said. “The thing that got me there was embracing the fact that that I am made up of half my dad, and a lot of my traits come from him.  So much of me comes from my father, and for so long, I didn’t like that about myself. I had to accept that it’s okay not to get along with somebody and still love them.”

And speaking of family, ‘Problem’ singer opened up about someone who she was much closer to — her grandfather, who sadly died after the interview.

“He was like, ‘You’re a star, I know in my heart you’re going to make this family so proud. You’re a blessing,’” Ariana recalled to the magazine. “And I was like, ‘Oh my God,’ and started crying, and I trusted it.”

In fact, Ariana even reached out to the magazine after her grandfather passed away, with a heartwarming message about reminiscing about him in the interview.

“This interview took place before I lost my grandfather. Reading it back now is, of course, very hard but I’m so grateful that I spoke briefly about some of the wisdom he shared with me in this interview,” she revealed.
