The Australian choreographer called for Atack to be voted off the programme, claiming that she was too "safe" with her performances on the ice.
The Inbetweeners actress, who was voted off the ITV1 reality show on Sunday, joked that she should be grateful Gardiner wasn't meaner to her with his comments.
"Jason is a lovely bloke. He is very nice backstage. A lot of it is panto and I think he does know what he's talking about," she told DS.
"He knows what he's looking for and is very particular. Unfortunately, he didn't see that in me, but that's not his fault. He's just being honest. He is right and I don't have great leg lines. Whether they are like a 90-year-old's, I'm not sure!"
She added: "Jason was actually quite easy on me compared to some of the other contestants, so I should be thanking him really. He was very nice at the end of the show last night - I don't have any hard feelings with him at all."
