Listen to Lady Gaga on iHeartRadio

It looks like Lady Gaga fans can look forward to a new breakup song.  The Mother Monster has released a teaser of a new song called "Swine." 

Hints on the star's Twitter page suggest that she plans to reveal the song in full this Sunday, the day at a performance in London.  Gaga shared footage of her rehearsals for it. 

The rest of the video shows the singer angrily banging on a drum set, screaming the word "swine."  She's also dubbed her performance "#SwineFest" and is expected to debut more from ARTPOP at the concert, which will be live streamed on iTunes around the world.
