Demi Lovato and Paulina Rubio each said goodbye to a contestant on Thursday night's X Factor results show.
The first to go was Khaya Cohen , who had been a member of Demi's "girls" category. She fell into the bottom two last week, but staved off elimination by winning her sing-off with Rachel Potter .
Thursday's sing-off pit two of Paulina's "boys" against one another. Tim Olstad performed "You Raise Me Up" by Josh Groban , and Carlito Olivero covered "Beneath Your Beautiful," by Labrinth and Emeli Sandé . Tim was ultimately dismissed by an emotional Paulina.
All of Simon Cowell and Kelly Rowland 's remaining acts will return next week.
The night's musical guest was U.K. X Factor creation One Direction , who performed “Story of My Life."
It will be "big band week" on The X Factor next week. It begins on Fox Wednesday night at 8 p.m. Eastern time.
