Take That have been lined up to play the final of The X Factor - after already recording a slot on the final of rival show Strictly Come Dancing.
The trio will perform on Saturday December 13 during the first stage of the ITV singing contest's climax, which will see band member Gary Barlow returning to the show after quitting as a judge following last year's series.
But the announcement that the group have been added to the line-up comes six days after they filmed a pre-recorded performance with a hits medley which will be slotted into the Strictly final next week.
And their appearance on this weekend's X Factor comes less than three weeks after the group last appeared on the show, when they performed latest single These Days on a results edition.
This time Gary, Mark Owen and Howard Donald will be singing their 2007 hit Rule The World, as they open Saturday's show accompanying the three finalists, Andrea Faustini, Ben Haenow and Fleur East.
Over this weekend, The X Factor shows - which include the results show on Sunday in which the winner will be crowned - will also feature Ed Sheeran, Sam Smith, One Direction, Meghan Trainor, Olly Murs and Demi Lovato.
There had been reports that programme bosses had struggled to find a final act to complete the line-up. At one stage there had been speculation that Madonna might perform.
Take That are currently at the top of the album charts with their new release III, and have been on the promotional trail with a number of TV appearances and a Radio 2 concert.
Sheeran will be playing his song Photograph, Trainor will sing her chart-topper All About That Bass and Smith will perform Stay With Me.
The final will be broadcast from Wembley Arena.
