Tess' love for Strictly runs deep – speaking to The Guardian in 2010, she admitted she genuinely cared about each and every contestant's performance.
She said: "Without sounding twee, I do care about them because I see them petrified in the morning, sitting in make-up, mute and waiting to get it over with. They've slogged their guts out most of the time.
"You get to know them and their families and you see pictures of their kids and they meet your kids. Yeah, you end up rooting for them."
Back in 2013, Tess turned up the heat in a sultry backless number during a Strictly Come Dancing event at Elstree Studios in London.
