Mother Monster Lady Gaga is back in the studio recording her brand new album with music legends such as Diane Warren and Nile Rogers and her mentor RedOne. Now her song, Till It Happens To You, has found its way on the web. It was penned by Diane Warren and is part of the upcoming documentary The Hunting Ground, which premieres tonight at Sundance. 

It is an emotional song and we can see clearly that it was written by Warren.
