Gaga's leaked Applause released
Lady Gaga has been forced to release her new single Applause early because it was leaked on the internet, calling it a "pop emergency".
The Born This Way singer was about to release her comeback single after time off to recover from a hip op, but had to bring forward the launch because of the leak, The Wrap said.
Applause was set to be released on August 19, but when Gaga discovered what had happened she put it out the same day, on August 12.
The 27-year-old sent a series of tweets rallying her fans, the "monsters", to spread the word about the new release date.
She tweeted: "A pop music emergency is underway 911.
"911 summon the monster troupes.
"Due to hackers a number of low/high quality leaks... we issue this pop music emergency... monsters spread the word.
"My new single Applause is out today and can be heard on United States radio in 15 minutes. International radio to follow."
The album Artpop which Applause is taken from is due out on November 11 with an accompanying app set to be launched on the same day.
