All those twirls, all that two-stepping...
It's really taken its toll on Rachel Stevens.
The Strictly Come Dancing star has reportedly shed so much weight during her stint on the show that she's constantly having her costumes altered.
Rachel seems to be in fairly high spirits about her new fitness regime.
She told Heat magazine: "Being in Strictly is a dream come true and has done wonders for my figure and general fitness.
"I'm in better shape than ever and it's so much more fun than going to the gym."
However, an insider on the show says: "Rachel has slimmed down a lot.
"Wardrobe have had a nightmare – they're doing constant refits because her body shape's changed so much."
Dance your socks off Rach, if that's what makes you happy.
Just don't go getting all waif-like on us.
