Iggy Azalea was "difficult" on the set of her 'Pretty Girls' video with Britney Spears.

The 25-year-old rapper reportedly angered crew on the set of the video, which was shot in California earlier this year, after she "totally took it over" and "ordered everyone" around
A source revealed: "Iggy was difficult with respect to direction of [the] video. Everyone just got fed up and didn't want to deal with it. Britney, being a veteran artist, was tired of arguing."
A second source added: "'Pretty Girls' was Britney's song and video but Iggy totally took it over as if it was hers. Iggy ordered everyone -- including Britney -- around as if she was directing the video."
The 'Piece Of Me' hitmaker was also bossed about prior to their performance at the Billboard Music Awards in May, as the blonde beauty dictated which outfit she wore.
A source told Us Weekly magazine: "Britney is such a fan that she listened to everything Iggy said."
Meanwhile the pair have recently hit out at each other after their collaboration failed to top the charts, with Iggy claiming it "flopped a little bit" because they didn't promote it enough.
She wrote on Twitter: "its difficult to send a song up the charts without additional promo and tv performances etc. unfortunately im just featured...
"i would have enjoyed performing it alot, i think it got off to a powerful start. but you need content to compete in 2015. (sic)"
Hitting back, Britney tweeted a snide message in referral to Iggy's North American 'Great Escape' tour, which she recently cancelled because she wanted "a break".
She wrote: "Can't wait to get back to Vegas. So thankful I have shows for the rest of the year to look forward to... #YouWantAPieceOfMe (sic)."
