Jessie Jwas apparently left fuming ahead of her performance onKitty Brucknell, before she had sang the song herself on the ITV programme.

A source told the newspaper: "Two weeks ago when Misha was in the sing-off with Kitty Brucknell, she wanted to sing Who You Are, she loves Jessie and sees her as an inspiration so it was a real honour."
"But Jessie and her camp had wanted tonight to be the first time the track was performed on The X Factor. It was a bit of a mix-up and not really anyone's fault, but Jessie wasn't happy."
They added: "She's too nice a person to say anything to Misha, but if they meet it might be a touch awkward at first."
Jessie has since reacted to negative Twitter comments regarding her performance of Who You Are on The X Factor, tweeting: "Its funny that people that follow you tweet you but don't @ you when there slagging you off."
"I WAS pitchy last night and its the first thing I said when I came off stage. The track was so low in my ears I couldn't hardly hear it. I am a realist and I'm NOT perfect."
The 23-year old added: "I'm growing and learning and I'd rate half the artists more if they had the guts to say s**t to my face…"
