Britney Spears will perform at the iHeart Radio Festival alongside Drake and Ariana Grande on September 23rd and 24th. She will close out the show on day two. That's big. Brit Brit is performing at a music festival for the first time in like 10 years.It's probably going to be pre-recorded. So fans have to wait two months for a performance which may not even be live. A performance at the VMAs seems unlikely because she's very Vegas-bound these days. New single 'Make Me' might even lose some momentum. It would have made more sense to debut it at the Billboard Music Awards. This week, the track debuted at #17 on the Billboard Hot 100 with 96,000 copies sold.
