The TOWIE star is seen wearing a bright pink sparkly dress as tiara as she returns to the show.
James Argent’s on-off girlfriend is known for dramatically falling on the show when she appeared on it in January this year.
Holly, 38, looks amazing in the clip, dressed in a plunging nude-coloured dress.
The pair tell viewers: “The greatest show on ice is back with a real Christmas cracker.”
John Barrowman is also seen in the video as he makes his debut on the judging panel.
The I’m A Celebrity star is replacing Jason Gardiner, who quit the programme last month.
He will be joined by head judges Jayne Torvill and Christopher Dean and dance choreographer Ashley Banjo.
Speaking about his new role when the news was announced in September, Barrowman said: “I am so excited to be returning to the Dancing On Ice family. Unlike most I have been through the rigorous task of skating live as a contestant in the first series.
“This is a thrilling adventure for me and I hope to bring a Fresh, Fun and Fab-u-lous angle to the judging panel.”
Also appearing on the Christmas special will be X Factor star Ray Quinn, who won the show in 2009 and Hollyoaks star Jake Quickenden, who was champ back in 2018.
The exact date of the Christmas special is yet to be revealed. However, as the show is usually on a Sunday, it is likely to be on December 22, 2019.
