It is the third appearance in the dance off for Daisy but the first time for Greg, with the pair join second-bottom on this week's scoreboard.
On Saturday, Greg and pro partner Natalie Lowe performed a Paso Doble to 'Tamacun' by Rodrigo y Gabriela to score 31 points from the judges.
Daisy and her pro dancer Aljaž Skorjanec had performed the Salsa to 'Groove Is In The Heart' by Deee-Lite, also scoring 31 marks from the judges.
As usual, the results from the public vote were added to the judges' scores to decide the bottom two in the dance off tonight.
First to be announced as in the dance off was Daisy. "I'm just hoping it's not the third and final dance off. I loved that dance," the model told host Tess Daly.
Judge Darcey Bussell encouraged: "My advice would be soften those knees to avoid balance issues, smile and enjoy it."
Greg was revealed to be joining Daisy in the dance off, his first time in the bottom two. Craig Revel Horwood advised him: "Add less panic, try and land on that last beat and deliver a powerhouse performance."

Both Greg and Daisy then reprised their Saturday night dance for the judges, who decided who should stay in the competition.
And it wasn't a unanimous decision as the panel Craig and Darcey saved Greg whereas Bruno backed Daisy.
It left head judge Len to make the final decision, saving Greg and leaving Daisy to go home.
