Lady Gaga fans have been given a preview of her new track Til It Happens To You, after it was apparently leaked online.

The Mother Monster recorded the song for the soundtrack of a documentary called The Hunting Ground - which studies the lives of young people affected by rape.

[related]Tweeting in reference to the song and movie last month, Gaga wrote: "Till It happens to you, you don't know how it feels."

And she has previously opened up about her own experience of abuse at the hands of a record producer.

Appearing on Howard Stern's show in December, she said: "I don't want to be defined by it. I'll be damned if somebody is going to say that every creatively intelligent thing that I ever did is all boiled down to one d**khead that did that to me.

"It wasn't until I was a little bit older that I went, 'Wow, that was really messed up... You were 20 years older than me. I was a kid.'"

Fans have compared the new track to the work of Lana Del Rey and it appears to have been given a warm reception.
