Figure of fun? Miranda Hart to bust the festive fat with her own fitness DVD

Miranda Hart may be the least likely celebrity ever to star in her own workout DVD.

The comedian, 40, is following in the footsteps of Davina McCall and Natalie Cassidy with a Christmas fitness DVD.

A source told The Sun: "Miranda is a woman of many talents. But even her biggest fans will be surprised that she is doing this workout DVD. Washboard stomachs and finely toned biceps are not something you would normally associate with her.

"But whatever the routine ends up being, there is one thing that it will definitely be: funny."

Last year, Miranda vowed to lose three stone by training every Monday.

In 2010, she completed a 1,000-mile bike ride from John O'Groats to Land's End for Comic Relief - joking that she couldn't find any of her muscles when she was training for the epic journey.

She said at the time: "I was very sporty at school but things have gone downhill since.

"Suddenly I was forced into training sessions which involved very worrying terms like 'squats', 'lunges' and 'core muscles'.

"It turns out I had no muscles at all - we couldn't find them."
