When a fan tweeted that the song flopped, Iggy replied, "Its difficult to send a song up the charts without additional promo and tv performances etc. unfortunately I'm just featured...I would have enjoyed performing it a lot, i think it got off to a powerful start. but you need content to compete in 2015."
Britney did not directly respond, but she did issue this subtle clap back, utilizing some of her song lyrics in the hashtag.
Ouch! Some have also speculated that the 'having shows to look forward to' bit is a jab at the fact that Iggy canceled her 2015 tour.
Can't wait to get back to Vegas. So thankful I have shows for the rest of the year to look forward to... #YouWantAPieceOfMe— Britney Spears (@britneyspears) June 29, 2015
Something tells us there won't be a second collab between these two "Pretty Girls."
