It was a tense sing-off that saw X Factor favourite Ben in the bottom two, singing for survival against Louis' group, Eton Road.
With Louis and Sharon voting to save their own acts, it was Simon who had the deciding vote.
Having previously tipped Ben to be in the final, Simon had the chance to send him home and protect his acts. But he decided to save the young rock singer and send home Eton Road.
Mentor Louis Walsh revealed that he would manage Eton Road and make them stars.
It definitely isn't the end of the road for Eton Road...!
