Despite admitting she was the least technically gifted dancer the openly gay Scottish comedian has made it to week nine and a coveted place on the Blackpool special.
Tonight she will attempt Scott and Fran’s Paso Doble from the iconic film Strictly Ballroom with her partner Kevin Clifton inside the seaside town’s iconic Tower Ballroom.
But her lasting legacy could be something far more profound.
Susan, 43, is the first gay female to appear on the smash hit BBC One show and her trailblazing could prompt a sea change.
She said: “It has been incredible to have my wife sitting in the audience watching me in the same way that Ruth [Langsford] or Charlotte [Hawkins] have had their husbands there.
“That’s a pretty major thing for the biggest show on TV.
“I am the first openly gay woman to take part in Strictly and I think that has had a pretty huge impact.
“Kids will be sat at home thinking, ‘it’s just what happens’.
“Whatever happens in the future I think that is remarkable.”
Same sex couples already participate in Dancing With The Stars, the American version of Strictly.
Many think it is inevitable the same thing will happen here, potentially as early as next year.
Susan added: “Sandi Toksvig, Sue Perkins and Claire Balding are some of the most loved people on TV, so I really think the British public is cool with these things, and it has been great seeing people treat me simply as a woman dancer.
“I only ever wanted to dance with Kevin [Clifton] but if it means that next year we see the first same-sex couple, great.
“But that’s for the celebrity and the show to decide, it can’t be forced, but if it happens then great.
“My time on Strictly has certainly gone on far longer than I thought.
“Before we started I was hoping to make it through the first few weeks and maybe get to Movie Week because I thought I wasn’t particularly well known with the audience.
“It wasn’t that I thought I wasn’t good enough, it’s just compared to other familiar faces I was perhaps less well known and people weren’t going to bother voting for me.
“As it turned out I was wrong. I genuinely think it’s all down to the genius of Kevin.
“I am certainly the least trained dancer but wouldn’t say I am the worst dancer.
“You hope people like you but for me it’s about emotion and putting that into the dance.
“I want people at home to feel something and I hope they have.”
