The X Factor's top 12 acts will be announced after the top 16 acts perform tonight.

The top 16 were announced following the conclusion of the new Four Chair Challenge on Oct. 10.

During the Four Chair Challenge, each act finished their performance, then learned if they were "safe" or were eliminated. Even when told they were safe immediately following their performance, they still faced being eliminated if another group outperformed them afterward.

When episode 9 aired on Oct. 10, judge Simon Cowell selected the top 4 out of his final 10 group acts as the Four Chair Challenge ended. Judge Demi Lovato was forced to make swaps and eliminate singers she had previously expressed were her favorites during episode 8. Several contestants surprised the Glee guest actress and performed better than previous weeks.

Kelly Rowland and Paulina Rubio made their final four contestant picks the first week the Final Four Challenge was introduced the week before.
