Iggy Azalea's collaboration with Jennifer Lopez was "surreal".

The Aussie rapper - who released the video for the pair's new single Booty last week - has confessed she found working with the 45-year-old singer hard to come to terms with as she grew up listening to her music.

However, the Fancy hit maker was soon put at ease by Lopez's "down-to-earth" attitude and believes she will stay good friends with her idol following the collaboration.

When asked about the success of the duo's latest offering, she told E! News: "I did (expect the video to blow up) but only because I'm a massive fan of Jennifer and, you know, to me she's iconic, so I think anything she does deserves to be spoken about.

"Jennifer really surprised me. I thought that she would be like a super-diva, and she was so down to earth and lovely and she didn't have a crazy ride or anything extra, she just got on with it and she was so sweet.

"I feel like I've gained a friend out of our collaboration and I had a very surreal moment filming the video with her because she's somebody that I've sung her music in cars with friends and in bedroom mirrors over the years. It was really great to get to do this with her."

Meanwhile, Azalea, 24 - who, in addition to Lopez, has already teamed up with a host of superstars, including Rita Ora, Ariana Grande and T.I. - revealed she recently did a duet with another "pop queen" Ellie Goulding for new film Kingsman: The Secret Service to be released next year.
