Iggy Azalea and Charli XCX's Fancy may have been last year's summer anthem but unfortunately for Britney, her and Iggy's collab hasn't received such acclaim.
Pretty Girls may have gained over 78 million YouTube views for its music video but only got as far as Number 29 in the Billboard charts.
Responding to a fan on Twitter, Iggy made it clear what she thought of Pretty Girls' mediocre performance in the charts...
"its difficult to send a song up the charts without additional promo and tv performance etc. unfortunately im 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."
Eager to show that her opinions don't affect her friendship with Britney, Iggy also Tweeted; "Genuine friends have genuine opinions. Its possible & healthy to have differing thought without it being bitchy or shade."
Poor Iggy. Didn't she realise Britney wouldn't feel the same way? The 33-year-old mother of two hit back at Iggy with her own Tweet; "Can't wait to get back to Vegas. So thankful I have shows for the rest of the year to look forward to.. #YouWantAPieceOfMe."
On the upside, Britney's residency at the Planet Hollywood Resort and Casino has been extended for another 2 years thanks to the success of her Her Piece of Me concerts.
She may no longer be a Top 20 chart topper but she's got a great fallback as a Vegas showgirl!
