Jessie J has said there's not enough "constructive criticism" on this year's The Voice UK.
The former coach - who quit the singing competition last year after two series - thinks this year's coaches are being too easygoing on the contestants after watching Celestine Walcott-Gordon and Mairead Conlon perform her song 'It's My Party' over the weekend.
She wrote on Twitter: "Where is the constructive vocal criticism?! It was TOO MUCH! Vocally messy and too many runs and licks! Singers don't and won't improve if you continually say 'amazing' when it's not... Can't get better in a 'Yes bubble' (sic)"
Jessie, 25, went on to defend her controversial comments after receiving backlash from social media users, insisting vocalists - including her - need to be given criticism in order to improve.
She explained: "Every singer has to take criticism! Myself as an artist included! And I know if I performed 'It's my party' like Team Tom did on the battles that my team wouldn't say it was great. And I wouldn't want them to. The TRUTH is the only thing we can build from! (sic)"
Jessie quit 'The Voice' panel last year along with The Script's Danny O'Donoghue, paving the way for Kylie Minogue and Kaiser Chiefs frontman Ricky Wilson to join Sir Tom Jones and will.i.am.
The 'Wild' singer says her criticism of Team Tom's Celestine and Mairead is intended to be constructive, not hurtful, and she often listens to criticism of her own work.
She added: "I sometimes agree with people when their words may not always positive towards me. [...] listen BUT only when those words are constructive and come from a caring and loving place. (sic)"
