Here are all the pictures from Strictly Come Dancing 2018's Children In Need special.
Over the years the one-off show has seen Strictly performances from BBC Newsreaders, the Stars of Call The Midwife, Blue Peter presenters and more.
For 2018, the Children In Need special will feature the stars of Boyzone.
As announced earlier this month, the pop legends will join forces with the Strictly professional dancers as they compete against each other to win the Pudsey Glitterball Trophy 2018 for BBC Children in Need.

Ronan Keating will be partnered with Gordana Grandosek, Shane Lynch will dance with Luba Mushtuk, Keith Duffy will take to the floor with Nadiya Bychkova and Mikey Graham will be dancing with Katya Jones.
Boyzone said: “We are so excited to put on our dancing shoes and learn some new moves for the Strictly dance floor!
"It’s an absolute honour to be a part of such a special evening and we can’t wait to show the nation what we’ve got in store.”
In the Strictly Come Dancing Children In Need special, the celebs taking part will perform one group dance with their pro dancer.
Just like in the main show, judges Shirley Ballas, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood will be on hand to offer their opinions.
The winner will then be declared who will lift a special trophy.
Presented by Tess Daly and Claudia Winkleman the special show will feature as part of the Children in Need 2018 Appeal Night on BBC One.
The BBC Children in Need Appeal Night is tonight, Friday 16 November 2018 live from the BBC’s Elstree Studios on BBC One, with the Strictly special airing during the telethon.
Stand-up comedian and presenter Rob Beckett is set to join Graham Norton, Tess Daly, Mel Giedroyc, Ade Adepitan, Rochelle and Marvin Humes in presenting BBC Children in Need’s 2018 Appeal from 7:30PM tonight.
