In the world of the selfie-obsessed celebrity, the motto has to be: "If you can't beat 'em, join 'em – then beat 'em" – especially when it comes to showing of your post-baby figure.
The mum-of-one, 31, posted a pic on her Instagram to boast about her slim pre-Christmas stomach.
But not content with simply lifting up her top to display her trim tummy, Imogen - who has never been afraid of baring her body - stripped off to pose in just her pants.
The full-length pic shows her standing side on wearing only her pink knickers and covering her chest with an arm. Imogen, who gave birth to daughter Ariana in February, captioned the snap: "No carbs after 6...!! flat tum ready to indulge over the Christmas period.
