Robbie Williams will probably never be Back For Good with Take That but the lads may be giving fans a night they will Never Forget as it is thought they will team up for a special X Factor performance.
The band are thought to have agreed to perform on the X Factor stage with Robbie after it was revealed that the former boy bander had joined the judging panel.
Having Robbie on the panel has been a huge coup, but obviously backstage everyone has been talking about whether or not hes going to sing at some point, a source close to the ITV show claimed.
It seems a shame to have one of the biggest pop stars on the planet sat there and not hear him, so theyve been plotting a surprise for the end of the series.
Speaking to The Sun, the insider added: Its a while since they got together and nobody is completely sure when it was going to happen for the anniversary so itll be a massive moment.
And maybe one that will bring those falling ratings back up?
Take That, made up of remaining members Gary Barlow, Howard Donald and Mark Owen, have been in the studio recently cooking up something special to mark the occasion of their 30th anniversary, and it is thought that not only have they created new music for their Greatest Hits album, they will also be putting a brand new spin on some old classics as well.
Front man Gary teased the completed TT30 project on Twitter.
Our Greatest hits album is now finished and mastered, he said.
Every track has had a face lift. Some have been completely re recorded. 3 brand new songs. Theres guests and lots of interesting links between songs. What a journey #TT30.
