Speaking to Fairfax Media, Wilson said she was put on the same table as the Burke's Backyard star for the 1996 Logie Awards.
"He seemed like a nice bloke," she said. "The awards ceremony started and I remember I was wearing a navy blue velvet maternity evening dress.
"I turned around to look at the stage and I said to Don – because we'd been talking – 'Please excuse my back' because I was turning my back to him.
"He said, 'Not at all. Do you mind if I lick it?' "
Wilson said her husband was sitting next to her and heard what was said.
"It was gross," she said.
