"I was at the Soap Awards and I was wearing a green dress, and it was so tight that I couldn't wear knickers with it," Porter said. "It had a really low back and it was so low, a lady had to sew a stitch in.
"As I got out of the taxi, it ripped and I was like, 'Holy Jesus'. Nicole [Barber-Lane], who plays Myra, had to fix it to make sure my crack wasn't out."
Porter continued: "I was so conscious of it. You know when you've got no knickers on and you want to tell people? It's like a rule. You just want to whisper to people, 'I've got no knickers on'."
Asked what the naughtiest thing she got up to was, Porter said: "There are too many naughty things. Probably things I couldn't say. Wearing no knickers is pretty naughty."
Porter also revealed that she used an unusual code when talking about her upcoming stint on Dancing on Ice before it was made public.
"This is the first time I'm able to say I'm doing it," she said. "Do you know what my code words have been for this?
"'Taking it up the bum!' I've been like, 'Next week, I'm taking it up the bum. All week."
