The new Britney Spears-Iggy Azalea collab Pretty Girls has officially dropped, and the song may have the potential to be the official song of Summer 2015.

The catchy track officially dropped on iTunes today, two days after it was leaked early online, something that Azalea took to Twitter to address.

"I happened to have noticed that pretty girls, my song with @britneyspears has leaked and is on some radio stations etc. I'm really really happy to see so many people loving it but I also just want to clarify it's not an 'early' release it's a leak and if you can we would really appreciate everyone holding out until Monday to share links etc if possible (I know it's hard, I'm excited too!)" she wrote in a series of Tweets.

The track features both stars mixing their vocals together on the chorus, a rare occurrence for Azalea, who is best known for her rap tracks, Fancy, and Black Widow collab with Nicki Minaj.

Azalea also addressed the fact that she was singing on the track on Twitter as well, saying she hoped it would be more obvious to her fans when she and Spears perform it live for the first time at the Billboard Music Awards on Sunday, May. 17.

"Also for the record brit and I are both singing the chorus's together...i guess you guys aren't used to hearing my singing voice :-). Saw some people missed that aspect, maybe when we perform it it will be more obvious hahaha," she wrote.

According to Billboard, the music video for the song (the reveal date has not been determined) will be an homage to the '80s cult classic Earth Girls are Easy.

Listen to the track below and be sure to sound off in the comments section. Is this definitely the song of Summer 2015?
