Kesha has lost her voice following three consecutive performances this week (begs23May16).
The Tik Tok singer has sung live a few times this year, but she stepped up her appearances this week by performing Bob Dylan cover It Ain't Me Babe at the Billboard Music Awards on Sunday (22May16) followed by two nights at Dylan Fest to celebrate the veteran's 75th birthday.
The three consecutive live performances have now taken their toll on Kesha and her voice is struggling to cope.
She posted a selfie on Instagram in which she is poking out her tongue, and wrote in the caption, "exahusted (sic). sleep time after no sleep for the past week. I've sang my little heart out and now my voice is gone. LOVE those of u who've been supportive and awesome. thank u."
Kesha appeared at Nashville's Ryman Auditorium on Monday and Tuesday nights to honour Dylan by covering his track I Shall Be Released and she gave both performances her all.
"No better way to celebrate Bob Dylan's birthday than to scream his poignant genius lyrics at the top of my lungs in the ultimate church of music, the Ryman," she wrote on Tuesday night.
She has also been recording music with the band Steelism this week. Kesha is currently unable to release her own material as she is locked in a legal battle with producer Dr. Luke over allegations of sexual and emotional abuse, which she filed in 2014. She is currently trying to get out of her recording contract.
She took a break from music following the scandal but has since performed at Coachella Music Festival and a Humane Society gala, and released a track with DJ Zedd.
