Britney Spears and Iggy Azalea have shared the video for their collaborative single ‘Pretty Girls’, which you can watch below.

In the video, Azalea plays an alien who lands on Earth and, with the help of Spears, adapts to 80s human life by crimping her hair and practicing her Valley Girl accent.

According to USA Today, Azalea and Spears initially connected after Spears saw Azalea’s Clueless-inspired video for ‘Fancy’.

"I had called my manager (Larry Rudolph) and had some ideas about doing a Valley girl-type video," Spears said. "It was really kind of funny, because I had just watched Clueless on TV, and was like, 'It would be so fun to do something like that.' Then I saw Iggy's video, and I thought, 'Oh my God, to work with her would be heaven sent.' "

"We just talked about a bunch of girl stuff. She's a very down-to-earth girl and very, very sweet," Spears continued. "She introduced me to her dog, we had wonderful salad and it was just fun girl time."

Azalea revealed that Spears had made it clear to her that she wanted to dress up and play a character in the video for their collaboration. "That was really important to her,” Azalea said. Spears just wanted to "let loose and not necessarily feel like she's playing Britney Spears."

Britney Spears and Iggy Azalea will be making their debut live performance of ‘Pretty Girls’ during the Billboard Music Awards, which will air on Sunday (May 17).
