Iggy confirmed the exciting news during an interview with Kiss 108, and even gave a tentative release date for the future collaboration of the century.
"I'm gonna go check [Britney] out in Las Vegas and hopefully I'll get to officially meet her," Iggy revealed. "We have a song that's going to be her first single coming out next year and I still haven't got to really have a conversation with her, so I'm hoping New Year's will be the time that I can get her in a corner."
She added, "We recorded a few different things and one of those just ended up being undeniably great so I think everybody will get to hear it at the beginning of next year."
Britney has also recorded a song for the upcoming Giorgio Moroder album, so it looks like we'll be getting a lot of new music from The Holy Spearit next year!
