'The X Factor', running from 7.35pm to 8.35pm, took 52% of the TV audience and peaked at 12.9m viewers, or 55%.
Viewers tuned in to see acts like geeky French waiter Fouad Djaoublia and his weird rendition of Mariah Carey's single 'Hero'.
Djaoublia's performance sent the judges and the audience into hysterics as he squealed out the song, making strange noises while repeating the lyrics.
He instantly became a YouTube sensation and garnered around 61,000 hits in less than 24 hours. His audition has now been viewed almost 200,000 times through various uploads on the video sharing site.
Videos of Fouad's performance are also available on ITV.com.
