Here'ss a look at how the Strictly Come Dancing 2016 couples have been getting on in their first few days of training.
The 15 celebrities on the Strictly Come Dancing 2016 line up were coupled up with their pro dancers during the weekend's launch and this week begin their first training sessions.
And for some it's been quite the eye opener with a LOT of tired feet.
There was an extra surprise for Olympian Greg Rutherford who was faced with a random drugs test as part of his 'day job', quipping: "Clearly they think I'm too good a dancer."
Elsewhere, Ore seemed to be struggling to remember the moves for his first dance while Louise Redknapp was coming to terms of having her body aching all over.
Here's a behind the scenes look at what's going on inside the training rooms, thanks to Twitter...
