The past and present X Factor judges have spent the last week practicing songs for next week's televised Children In Need gig in Manchester round at Gary’s house, according to The Sun.
A source said, 'Cheryl hasn't done much TV this year at all and it has been a while since she sang live on stage.
'She has been busy in the studio working on her next album so her voice is in good condition but she wanted to get some serious time together with Gary before next week.
'They will have a big section together on stage at the MEN. It is going to be special.'
