The 17-year-old beauty sparked fears she wouldn't be well enough to take to the stage after she was forced to pull out of a performance earlier this week having been put on voice and bed rest, but she's now claimed she's more than ready.

She told BANG Showbiz: "I don't know where this, 'I'm not going to be able to make it to the final' has come from, because I'm not going to not make it.

"I'm so ready to perform and yeah I've got a sore throat but it'll be gone by the weekend."

And Louisa's mentor Rita Ora - who joined the show as a judge after being poached from 'The Voice' by boss Simon Cowell - is desperate for her act to win.

Asked how it would feel to win her first series, she said: "That would be so f***ing awesome. I don't think I'd ever shut up for like a year. I'll be like, 'See Simon, you picked the right girl!' "

However, the 'Body on Me' hitmaker thinks Louisa has a great career ahead of her whether she wins or not.

Rita added: "We've found a star anyway. It'll be amazing for her to be the winner, but I don't think this will be the last time you see Louisa Johnson."

'The X Factor' final airs Saturday (12.12.15) and Sunday (13.12.15) at 8pm on ITV.
