Speaking at the recording of the launch on Wednesday night, Lisa said: "We'll see what Craig says [about my dancing]. But whatever he says, I can throw a good punch and I'm from the North so he should be afraid."
The actress said it was "wonderful" to be able to dress up for the show, having played rather less glamorous telly characters.
She explained: "All the characters I've played are mingers, so this is wonderful. Hair extensions, tans, glitter - it's brilliant.
"I'm in makeup for an hour and half just trying everything."
She added: "I want to be funky and shake my thing. It's a big thing, but I want to shake it."
