She survived the tense quarter final round which saw girl band 4th Impact dramatically exit the competition.
But while Louisa Johnson's weekend was not without its drama, the aspiring popstrel managed to put on a brave face as she greeted fans outside The X Factor's studios in London on Sunday night.
Despite having picked up a mystery illness, the 17-year-old contestant was all smiles as she left the studio in a mid-riff flashing crop top after finding out she'd made it through to the show's semi-finals.

Putting on a brave face? While Louisa Johnson's weekend was not without its drama, the aspiring popstrel managed to put on a brave face as she greeted fans outside the X Factor's studios in London on Sunday night
Beaming - despite the illness which saw her receive some criticism from Simon Cowell on Saturday - the blonde singer flashed her taut tummy as she mingled with fans outside the show's studios.
Wearing the same outfit she'd appeared in on-stage earlier that night, the pretty teen cut a fashionable figure in a shimmery metallic red crop top and high-waisted leather trousers.
Showcasing her flat tummy in the rib-grazing garment, the chart-topping hopeful avoided flashing too much flesh thanks to a large mesh panel detail across the garment's otherwise low-cut neckline.
Drawing further attention to her toned tummy, while also further showcasing her style credentials, the Louisa slipped into a pair high-waisted leather trousers that featured turn-ups and a belt detail.

Rounding off her outfit with a pair of high-heel stiletto shoes, the young singer accentuated her toned frame, while she also donned an olive parka to keep some of the chill weather at bay.
Wearing her blonde locks in her trademark tousled style, Louisa let her golden mane tumble down around her shoulders, framing her pretty face.
Wearing a natural palette of make-up, she highlighted her pretty features with a flash of mascara and a liberal application of nude lip gloss.
Posing for photos with fans, Louisa looked to be in high spirits despite finding herself on the receiving end of music mogul Simon's critical eye.
After having her performance of Justin Bieber's Love Yourself fell flat on Saturday night, the show supremo labelled her performance 'tense'.

'I'm not very well, sorry': After having her performance of Justin Bieber's Love Yourself fell flat on Saturday night, the Simon Cowell labelled her performance 'tense', with the teen admitting she was ill and suffering
Revealing that she was suffering from an illness, the teen apologised, saying: 'I'm not very well, sorry.'
However while she escaped the sing-off unlike her fellow 'girls' category contestant Lauren Murray, show bosses appear to be fearful for the young singer's health.
According to The Sun, Louisa has been kept in isolation by the crew to stop her spreading the mystery illness after both Lauren and show co-host Olly Murs reported flu-like symptoms.
A show source told the paper: 'Louisa is putting on a brave face but she can hardly speak. We're worried she could be too ill to continue next week. We couldn't give her a free pass to the final, there would be uproar.'
Before adding: 'If any of the other contestants come down with the same thing we will really struggle. Olly is also sick and struggling. The bugs going round at the moment are really nasty.'
However, despite concerns, Louisa remains the favourite with bookmakers to clinch this year's top spot on the show.
MailOnline has contacted a representative of Louisa's for comment, but have yet to receive a reply.
