Australian rapper Iggy Azalea has revealed that collaborating with Ariana Grande on the song 'Problem' was "amazing" because they got along so well when they worked together and the young singer is so talented.

Speaking to Rita Ora in a new interview for MTV News, the beauty explained that the duet had been talked about for around 12 months so it was great when it finally materialised: 

"Ariana’s amazing, she’s super sweet and she has an amazing voice and she’s a great girl to work with. We’d actually been talking about doing a collaboration for about a year. We spoke about me being on her first album and it didn’t end up happening and so it’s great to be on her first single. It’s a cool song, really good vibe.”

'Fancy' hitmaker Azalea, meanwhile, has just announced that she recorded a duet with Jennifer Lopez for the star's new album, which was a dream come true because she's a huge fan: 

"I love her. I definitely used to sit in my bedroom as a young girl and lip-sync Jennifer Lopez songs, so it’s very cool to have a song with her on her album."
