Kesha's mum Pebe Sebert's called for artists set to perform at the 2016 Billboard Music Awards - including Fifth Harmony and Justin Bieber - to boycott the ceremony after her daughter was barred from performing by Dr. Luke.
Kesha was originally set to take to the stage at the awards on May 22nd, but since she and Dr. Luke's label Kemosabe Records have been 'unable to come to an agreement' as to whether or not she can perform her mum says other acts should 'stood with' her and backed out themselves.
Taking to Twitter, Pebe said: "Wouldn't it be nice if other artists stood with Kesha and refused to preform if she is not allowed to sing!
"Are KEMOSABE's actions today the actions of a record label that is trying to promote the success of their artist?
"Wouldn't any record company fight to have their artist have the exposure to millions? Only if they wanted their artist to succeed!"
This all comes after Dr. Luke barred Kesha from performing as originally planned, with a statement reading: "Kesha accepted an invitation to perform on the show and she received written approval from Dr. Luke's record label, Kemosabe Records.
"Kemosabe subsequently rescinded its approval following a media report on Wednesday May 11 regarding Kesha's appearance on the BBMAs. Unfortunately, Kesha and Kemosabe have since been unable to come to an agreement for Kesha to perform on the show."
