Ke$Ha broke down in tears as she recorded a Bob Dylan track for a charity album.
The TiK ToK hitmaker is among a group of singers, including Miley Cyrus and Adele, who have contributed cover versions of classic Dylan songs to raise cash for Amnesty International.
And she has revealed her recording of Don't Think Twice It's Alright left her sobbing hysterically - she can even be heard weeping as she sings on the album.
In a video posted online by Rolling Stone, Ke$ha says, "Getting a chance to record a Bob Dylan song for Amnesty International was a massive deal for me... I pulled up (music-making software) GarageBand on my laptop and just sang through the song once and by the end of it I was just crying hysterically alone on my bed...
"I was weeping (during the recording), you can hear it. We just used that recording. We didn't record it into a professional microphone, nothing. (I) tried to sing it a few times but that magic was really in this first, genuine, distraught, emotional take that you guys are going to hear on the record."
