Chafford Hundred X Factor star Louisa Johnson blew away the audience on Saturday night with a cover of Billie Jean by Michael Jackson.

Judge Simon Cowell said: “I love moments like this when we can discover somebody like you,” after he and the three other judges gave Louisa a standing ovation.

The seventeen year old’s performance on the show has made her the bookies’ favourite to win X Factor, and she is now running odds of 6/5 with William Hill to win.

Fans have been going wild for the starlet, who is now, and over the weekend social media reflected the love.

It was Louisa’s second ‘official’ performance on the show, and so far four other acts have been voted off, with nine remaining.
