The This Morning presenter has been documenting her journey on this year's BBC series and yesterday was left stunned by her partner Anton Du Beke.
Ruth revealed that she had turned up to rehearsals in her gym attire prepared for another sweaty session in the dance studio but the professional dancer had a very different idea.
Anton left the 57-year-old speechless when he arrived in a three-piece black suit for the third day of rehearsals.
Speaking to her 367,000 followers in a clip posted on Instagram, Ruth explained: "So, here I am, day three of training, and I have my training kit on; a T-shirt and some leggings.

"And look at Mr Anton Du Beke, he's come in a flipping suit!"
The 51-year-old could then be seen twirling around in the background as he defended his choice of outfit.
"Well, it's just normal. It's just my work clothes. I'll tell you what, I'll go casual for you," he laughed as he began to take off his jacket.
Still not impressed, Ruth hit back: "Ooh fancy smancy. I'm feeling very underdressed now."

Trying to keep his partner in a good mood, Anton smiled: "But you are so glamorous."
It seems Ruth isn't the only Strictly Come Dancing star to share behind-the-scenes clips of her training.
Gemma Atkinson sent her partner Aljaž Škorjanec into a panic when her dancing shoes fell apart in rehearsal and had to super glue them back together.
