Many fans of both artists were really excited for September 6th, for they were under the impression that the collaboration song between Kendrick Lamar and Lady Gaga would be released that day.  Sadly, for whatever reason, the song is being delayed.  Gaga tweeted the disappointing news to her nearly 30 million fans.

The song should appear on Kendrick's upcoming album, good kid m.A.A.d city, which is set to be released on October 2nd, so maybe he felt like the song was too epic to release it so early.
