Lucy and Richardson will both compete against bookies' favourite Tamaddon in Sunday night's final after former EastEnders star Danniella Westbrook was voted off the contest at the weekend.
Speaking to The Sun about the pair's chances of victory, Gardiner commented: "With those pillocks, do we need to even rock up on Sunday? Can we just give Hayley the crown and go home?"
The outspoken choreographer also hit out at his fellow judges Karen Barber, Nicky Slater and Robin Cousins for choosing to save Lucy over Westbrook in the semi-final.
He complained: "Danniella wasn't as good a skater as Gary but was a better performer. We have three skating judges on the panel and only two performance and dance judges.
"So they decided to go with skating prowess over the dance performance and it annoys me as it is called Dancing On Ice. What people at home pick up on more is the dancing."
The Dancing On Ice final airs on Sunday at 7.45pm on ITV1.
