There's set to be one seriously fierce battle in the charts as pop divas Britney Spears and Katy Perry both dropped surprise new singles on the same day.
Music fans have been left giddy with glee as Katy, 31, unveiled her new Rio 2016 single Rise, while Britney, 34, released the first single from her forthcoming ninth studio album, Make Me.

Britney - the original pop princess, 90s kids might say - is currently in the lead with her track sitting pretty at number one in the iTunes chart, hitting the top spot within hours of its release.
The relatively slow but beat-heavy and catchy track features up-and-coming rapper G-Eazy, and is Brit's first new single since her collaboration with Iggy Azalea on Pretty Girls last summer.
Fans are chomping at the bit for her new album, too, which she's also teased with bits of another new song Private Show and an eye-popping, sexy clip.
And it certainly looks like old (or young) Britney is back, as the cover for the single sees her looking incredibly ripped with THOSE famously toned abs on display in a skimpy white sheet-like outfit against a desert backdrop.
The music star was left incredibly humbled by Make Me's speedy jaunt to the top spot on the charts, as she retweeted a grab of the list, adding: "This is an incredible feeling. Thank you, thank you, thank you!! #MakeMe."
Meanwhile, Katy's motivational number Rise, which will be used in US network NBC's coverage of the Games, is also set for a rise in the charts.
The up-tempo and typically Roar-esque song includes the lyrics: "When the fire's at my feet again, and the vultures all start circling/They're whispering, 'You're out of time,' but still I rise."
Speaking about her reasons behind the song, and its relevance to the Rio 2016 Olympics, she said: "This is a song that's been brewing inside me for years, that has finally come to the surface.
"I was inspired to finish it now, rather than save it for my next album, because now more than ever, there is a need for our world to unite. I know that together we can rise above the fear - in our country, and around the world.
"I can't think of a better example than the Olympic athletes, as they gather together in Rio with their strength and fearlessness, to remind us how we ALL can come together, with the resolve to be the best we can be.
"I hope this song can inspired us to heal, unite, and rise together."
Katy's new single - her first since 2014's This Is How We Do from her Prism album - has gone into the iTunes chart in the top 10, and is expected to head for the top five.
