Take That will perform with the bands in next weekend's Let It Shine live shows, it's been confirmed.
This weekend saw the first of three live finals as Gary Barlow's talent show nears its climax.
Ricki Lake joined as a guest judge for the first live show this weekend as the bands performed live for the first time and five boys went home.
Next weekend, former Pussycat Doll Ashley Roberts will join Let It Shine as a guest judge for the semi-final.
In the semi-final double bill the four remaining Let It Shine bands will go head to head in a bid to impress the judges and audience at home.
And the opening performance will see the remaining bands each perform a classic Take That hit, before they are joined on stage for a very special collaboration with Take That themselves, Gary Barlow, Mark Owen and Howard Donald to perform the song Shine.
Each band will then perform this week's songs, which will each include a dance break to keep their place in the competition.
In the results show the two bands with the lowest public votes will each perform a classic Beatles song in the dramatic sing off. The two bands will then be disbanded and the boys will be judged as ten individuals.
Gary, Dannii, Martin and Ashley will then decide which five boys will carry on as a band to the grand finale of Let It Shine.
Ashley Roberts said: “I’m beyond excited to be joining Let It Shine and taking a judging seat beside the brilliant Gary, beautiful Dannii and handsome Martin. I’m looking forward to sharing my experiences of being in a band and I can’t wait to see what surprises the boys have in store for their live semi- final performances!”
Let It Shine continues next Saturday night on BBC One at 6:55PM with the results 20:45PM again.
