All around the world, pretty girls unite: The long-awaited, highly anticipated latest offering from The Legendary Miss Britney Spears featuring — err, sorry, and Iggy Azalea has arrived...about two days ahead of schedule.

Hop in, roll the windows down and let's go downtown where our posse's at with Iggy Iggs and Britney, bitch.

Fancyney

Once that finger-snapping, synth-stabbing beat comes slapping into the speakers, it's immediately clear that The Invisible Men — the producers behind both "Pretty Girls" and Azalea's 2014 super-smash "Fancy" with Charli XCX — fancy themselves another, well..."Fancy." Consider "Pretty Girls" a natural continuation of the track that doesn't bite the original too hard, mixed with some of the cocky, call-out 'tude of Gwen Stefani's "Hollaback Girl." At last, Brit Brit got her wish to truly go the #SomethingMoreUrban route once again! Those trap-lite hi-hats and twinkly club beats are pure Hip-Hopney heaven.

Sure, okay, yes: "Pretty Girls" might not be Britney's Most Personal Song To Date. (#BuyBritneyJeanOniTunes.) That being said, it serves the exact purpose for which it is intended: It's a turn(t)-up track, perfectly suited for your night out with your (pretty) girls and armed with the kind of sassy, self-empowering lyrics that will supply Instagram captions for weeks to come, including but not limited to...

"Girls roll up! Windows roll down. Eyes on us! Jaws on the ground."

"LIKE BEES TO THE HON-AY." (Relax, BeyHive.) And of course...

"WE'RE JUST SO PRETT-AY."

Iggney

Iggy Iggs might be the subject of a whole lot of public scrutiny as of late for her freestyle skills and, uh, unintelligable live delivery. But I-G-G-Y still found the time in between beefing on Twitter with Papa John's to provide a short verse for B, including at least one solid reference to appease the Britney Army: "All the boys beggin' Britney, hit 'em one more time!" As for that last minute single cover switch from "feat. Iggy Azalea" to "& Iggy Azalea"? You can decide if Azalea's participation merits the ampersand.

Adlibney

Of the many good qualities of "Pretty Girls," the greatest of them all is Brit Brit's vocal delivery: Those swaggering verses especially, which vaguely recall the jazzy warble of "Mona Lisa," are a far cry from the highly filtered (and questionably very non-Britney) vocals of Britney Jean. This is undoubtedly our beloved Brit Brit singing once again, especially as she launches into those fantastic ad-libs during Iggy's verse toward the very end, which, for just the slightest few milliseconds, take us all time traveling speed right back to the beautiful Beltney days of 1999.

"Pretty Girls" isn't your typical Britney Spears lead single (not that it's even confirmed to be from an album), in that it's not particularly a sonic game-changer, a la "Gimme More," "Hold It Against Me" or "I'm A Slave 4 U." Instead, she's opted to supply a bout of breezy, radio-friendly fun rather than anything too left-lane. (For that, I'll kindly direct you to her genius cover of Suzanne Vega's "Tom's Diner" on Giorgio Moroder's upcoming album, Déjà vu.)

Still, the song's a no-brainer hip-pop bop. It already sounds like a hit that'll have the public flockin' — like bees to the hon-ayy, if you will. And if the two pretty girls touch down from their intergalactic journey in the upcoming Earth Girls Are Easy-inspired video just right, it'll be a surefire contender for Song Of Summer '15.

They're just so prett-ayyyy.
