After the rapper's recent concert in London, Iggy took to Instagram to thank her fans and revealed that she's just recorded a new duo.
"Hey London. I had so much fun with you guys... I think today has been one of the longest days of my life but It felt good seeing all your faces in the crowd. Thank you for the support," she wrote. "Also I recorded a duo after the show for another blondie and I can't wait till you hear it, now time for bed."
So, who is it? Britney Spears did post a picture of herself in the studio not too long ago, so maybe it's her? They wouldn't actually have to be in the same studio at the same time to record the duet, so the possibilities are pretty much endless.
Who do you guys think? Could it be Miley Cyrus?!
