Watch Lady Gaga's Emotional, Hugely Important Video For 'Til It Happens To You'

The just-dropped new video highlights the issue of campus rape.

Lady Gaga's brand new single, "Til It Happens To You," contains a powerful message. Its accompanying video -- which dropped alongside the song Friday (Sept. 18) at midnight -- is even more powerful.

Written and directed by "Twilight"'s Catherine Hardwicke, the video opens with a warning of its graphic content. "I hope that this PSA, with its raw and truthful portrayals, will send a clear message that we need to support these courageous survivors and end this epidemic plaguing our college campuses," Hardwicke said in a statement.

"Til It Happens To You," composed by Diane Warren, is Lady Gaga's first single of 2015. The song is the theme for the campus rape documentary "The Hunting Ground," which debuted in January. A portion of the song's sale proceeds will be donated to organizations helping survivors of sexual assault.
