Dawn has previously described him as "my anchor, my one true love".The pair are currently living Down Under while she works on the judging panel for Australia's Got Talent.
Dawn, 55, who married charity director Mark Bignell in April, says she dressed in tight, sexy lingerie at the beginning of their relationship.
When she first approached Grandage 18 months ago, she had only a vague sense of the show’s form.
But she knew she wanted it to have a narrative thread and to be well paced. It’s not like your awful, most feared auntie who’s just come back from Egypt where you have to sit and watch everything.
He just thought we were going to see bands as friends."I had to say: 'You see me sitting here, I like you, sitting there'. He was taken aback, let's put it that way."We are now married.
And he was completely shocked and couldn't speak."The Vicar Of Dibley star was honest enough to admit that Mark did get to see her pants in the end, but declined to go into details."He did see my pants! It all went according to plan." Dawn also opened up about her split from Henry, 54.
However, these days she prefers wearing something more comfortable."That's the awful thing about dating - tight underwear," she said in an Australian TV interview."We would all like to be in a big bra and pants and when you are in a secure relationship you can do that."Now I'm in the big pants again. I'm in the Bridget Jones's."Dawn admitted: "I did a little bit of excruciating dating, when you have to wear interesting pants, hadn't done that for years."Dates She also revealed she had been friends with Mark, 49, for years through her late mother Roma, but it took a while before he actually realised they were dating and she had to spell it out.
