Is that Davina? Of-corset is: McCall shows off her shrinking frame in tiny bodice as she larks around backstage at Got To Dance

She's previously insisted she never diets, instead relying on her intensive exercise regimes to keep her in shape.

And while her weight has fluctuated over the years, Davina McCall certainly looks on form at the moment.

The TV presenter, who turned 45 on Tuesday, took to Twitter the day after her birthday to show off her slim physique.

Slender: Davina McCall shows off her slim frame in a black and gold corset on Twitter as she larks around backstage on her TV show Got To Dance

She was in the middle of filming backstage at her TV show Got To Dance when she decided to pose in a black and gold striped corset with button detailing.

The bodice showed off her tiny frame and flattered her curves with its sweetheart cut over her bust.

Clearly feeling confident and pleased with her look, Davina completed her ensemble with some skintight black leather trousers and her hair worn down and straightened.

And she couldn't wait to share it with her Twitter fans as she posted the picture of her posing with a large grin and her hands on her hips.

Fluctuating: Over the years the TV presenter has showed off varying figures during her different pregnancies but has her strict fitness regime to thank for her now toned body

Taut: Davina, pictured last year, has managed to remain slim following the release of several successful fitness DVDs to get her in shape

She wrote next to the image: 'And they call this work #gottodance.'

And Fearne Cotton was so impressed she write back: 'HOT!!'

The day before McCall added following her 45th birthday celebrations: 'Had an awesome birthday. Thanks for your tweets! Back to work.. Promo for got to dance... Prob in outrageous outfit.'

And although it wasn't an outrageous outfit she did opt for the flamboyant corset.

Davina has previously fluctuated with her weight, especially after her different stints giving birth to her four children.

But she has been a great advertisement for her many fitness DVDs as she shows off her toned physique.

McCall is currently filming the fourth series of TV contest Got To Dance, alongside judges Kimberly Wyatt and Ashley Banjo, as well as JLS' Aston Merrygold who replaced Adam Garcia this season.

The latest season won';t air until next year but the auditions have already taken place across the UK.
