Jessie J addresses X Factor 'out of tune' criticism
Jessie J has responded to critics who said her performance on last week's X Factor was out of tune.
The singer said: "I was on X Factor on Sunday. Afterwards I went on Twitter, and so many people were attacking me because I was pitchy.
"It [the performance] was out of tune, but I've never mimed and I'm proud of that."
The 23-year-old, whose real name is Jessica Cornish, was speaking at BBC Radio 1Xtra Live in Brixton.
She added: "I would never surround myself with people who tell me I'm perfect because I'm not and I don't want to be.
"I'm 23, and sometimes I sing out of tune. Sometimes I say stuff that I shouldn't and sometimes I'm going to make mistakes."
Jessie J made the comments before performing her current single, Who You Are.
She said: "This next song, I hope it is in tune because that's the way it's supposed to be sung.
