Currie and Vincent Simone failed to impress the judges with their Latin routine on Saturday, only scoring 17 points.
Horwood hasn't held back on his criticism of the ex-Conservative MP, describing her dancing as like "a granny at a wedding".
"I think the producers were wise to cut out my comments [on Saturday]. She was writhing around to no sort of effect. It was all a bit granny at a wedding," he told Zoe Ball on It Takes Two.
"She has some movement, but it's all landing in the wrong places at the moment. I do hope she improves. I hope it's less spanking and more dancing."
He also blasted Nancy Dell'Olio's debut dance, which involved her and Anton Du Beke tripping over a feather boa.
"I would have wrapped it around her neck and strangled her with it," he joked. "Don't use props and don't ever think about a boa ever again. It was a disaster.
"I would suggest that they do very simple choreography and some simple steps."
Horwood was more complimentary about Russell Grant, who he described as performing like a "camp drag queen".
"He does have some inner body soul movement. So it's a great start. I'd just like to see some more basic moves and less of the disco," said the reality TV judge.
