This weekend will see Louisa take to the stage for the final time as she battles it out against Che Chesterman and Reggie 'N' Bollie for the coveted winner's title.
Naturally, RIta, who is mentoring Louisa in the competition, said she is backing her girl to win, and revealed she wouldn't stop bragging to the show's boss Simon Cowell if she did.
Speaking to Reveal at the X Factor red carpet event at Hilton London Wembley, Rita said: "That would be so f**king awesome [if Louisa won]! I don't think I'd ever shut up for like a year. I'd be like, 'See Simon, you picked the right girl!'"
Of course, Louisa is facing some tough competition, but Rita said it actually doesn't matter who wins because she already knows that Louisa will have a successful career.
"Regardless, I think we've found a star anyway," Rita continued. "You can't predict the future and it would be amazing for her to be the winner, but I don't think this will be the last time you'll see Louisa Johnson!"
Catch the X Factor live final this weekend on Saturday 12 December at 8pm on ITV.
