Lady Gaga declares 'pop emergency,' releases 'Applause' earl

The decision comes in the wake of her new single leaking on the internet over the weekend.

"Applause," the first song off of Gaga's upcoming album "ARTPOP," was originally supposed to come out Aug. 18. The full album – along with an accompanying app – is set to be released Nov. 11.

Gaga alerted her fans to the leak and then changed the single's release date via Twitter on Monday. (Spelling, punctuation, and capitalization are all original.) Her tweets:
