Vogue Williams and Harry Aikines-Aryeetey have been announced as the third and fourth celebrities taking part in this year's Strictly Come Dancing Christmas special.

Six celebrities will be paired up with pro dancers for the annual festive contest, with comedian Josh Widdicombe and Drag Race star Tayce having been previously announced.

The next to be confirmed for the lineup is presenter and fitness expert Williams, who will team up with Strictly favourite Carlos Gu.

"I'm so excited to join the Strictly family!" she said. "Carlos would have more of a chance of winning a Nobel prize than turning me into a good dancer but I am determined to try my very best! I'm loving it so far - bring on the Ballroom floor!"

The fourth celebrity to be announced is Aikines-Aryeetey, a former Team GB athlete now better known as Gladiators star Nitro, who has been partnered with Nancy Xu.

"STRICTLY... ARE YOU READY?! Nitro's blasting onto the Ballroom floor this Christmas!" he said, adding: "I'm swapping my trainers for dancing shoes, and trust me, I'm bringing the power, the energy and the moves!

"This December I'm gonna light up that dancefloor and crank the Christmas spirit all the way UP. Let's do this!"

The special will be filmed early next month for broadcast on BBC One on Christmas Day.
