With less than a month until the grand finals, the pressure is mounting for X Factor hopeful Sam Bailey.
This weekend will see the seventh live show in the competition and tonight 36-year-old Sam will be singing Bleeding Love, by Leona Lewis.
The mother-of-two, from Leicester Forest East, said: "It's really, really tough this week. It is a big one, the pressure's on.
"I am nervous, I'm not going to lie, but I'm looking forward to going out there and singing such a big song."
With the theme this week being 10th anniversary, the contestants are celebrating a decade of The X Factor.
As such, each hopeful is singing a song by a finalist from a previous series.
"I wanted to do a Leona Lewis song – I'd said it before I found out," said Sam.
"She's another one of my idols and I'm singing one of her songs, it's mind-blowing.
"It is a great opportunity and an honour to sing a Leona Lewis song."
During the week, Leona visited the X Factor house in London to meet Sam before her performance.
"I got to meet her and she gave me a few tips," said Sam.
"She told me to put the emotion into the song, to strip it back.
"I like to belt songs out, so it will be a challenge."
Last year, Sam took her eight-year-old daughter Brooke to see a Leona Lewis concert in Nottingham.
Sam said: "I'm singing this one for my little girl – I just want to do her proud."
This weekend, members of the Leicester City squad will be travelling to London to support Sam during the results show.
Foxes players Jeff Schlupp, David Nugent, Andy King and Paul Konchesky will be in the crowd rooting for Sam tomorrow.
Sam said: "I'm so excited for the footy lads to come down.
"They are my idols – I can't wait. I'm going to be star struck to hell."
Her husband, Craig Pearson, 40, said that he hoped Sam would "steal the show" this weekend.
He said: "Sam has told me this is probably going to be the hardest song she will sing in the competition but, touch wood, she will do great again.
"The pressure is heating up for Sam and I think it is worrying her.
"We just need everyone to keep voting – it's keeping Sam's dreams alive.
"We really appreciate all of the support she is getting, we can't thank people enough."
To see Sam perform, watch ITV tonight and tomorrow, at 8pm.
