Britney Spears returns with a summer anthem for all the "Pretty Girls," and she has "Fancy" hitmaker Iggy Azalea holding her down. On the bubbly track, the duo rep women from Aussie to L.A. as they let the world know how bossy pretty girls are.

"Thank you all for the amazing feedback on #PrettyGirls!! Going to bed now with a smile on my face. Have some more surprises coming soon!" wrote Brit after dropping the single.

"Pretty Girls" is the lead offering from Britney's forthcoming ninth studio album, due later this year. A video will be arriving soon.
