X Factor: Finalists To Perform With Their Mentors?
The final 3 acts will apparently duet with Kelly, Gary and Tulisa...
The newspaper claims Amelia and the Destiny's Child star will sing Tina Turner's River Deep, Mountain High, while Little Mix and Tulisa will perform a medley of two Alicia Keyssongs - If I Ain't Got You and Empire State If Mind.
Collins and Gary are still yet to decide what to sing for their duet, with sources claiming they have been rehearsing Take That tunes Never Forget and Greatest Day.
An insider revealed: "It's going to be more pressured than ever. The acts will be singing in front of 10,000 people - and with their mentors."
"The judges will be nervous as well because the song could be the difference between winning and losing."
They added: "And on top of that, Simon Cowellwill be watching from LA. So the judges are almost auditioning for their places on next year's show as well."
JLSare also confirmed to perform at the final.
