Kesha Covers Lady Gaga's 'Til It Happens To You'

(Radio.com) Kesha performed an emotional cover of Lady Gaga's "Til It Happens To You" on Saturday (May 7), at the Humane Society of the United States Gala in Los Angeles.

The evening honored songwriter Diane Warren as Humanitarian of the Year and Kesha was one of several artists, including Leona Lewis and Aerosmith's Steven Tyler, who performed Warren's hits.

"I want to dedicate this song to every man, woman, child and animal that has ever been abused," the singer said before performing the song. Warren, who co-wrote the song with Lady Gaga for the documentary "The Hungint Ground," accompanied Kesha on piano.

"I get letters and Gaga just told me, too, [that] there's not a day that goes by that people aren't stopping her and thanking her for the song," Warren said. Read more here.
