Gaga tweeted the artwork for the song yesterday, adding "Another shot before we kiss the other side. I'm on the edge of something final we call life".
Only last week, Gaga premiered the video for her previous single, 'Judas' — but 'The Edge of Glory' apparently isn't a new single, as such.
The Guardian reports that Gaga's UK spokesperson clarified: "The Edge of Glory is the first track of an iTunes Countdown promotion running in the lead-up to the release of the album Born This Way on 23 May."
So it's a new song that you can buy from iTunes from tonight. But it's not a single.
In other Gaga news, the singer has told the Associated Press that another new song, 'Americano', was written in protest over a controversial Arizona law. "I don't stand by many of those unjust immigration laws in my country," she said.
