Former glamour model Imogen Thomas has always been the owner of some enviable curves, but her recent weight loss is causing concern amongst some of her followers.

The mum-of-one shared make-up-free gym selfie where she appeared much slimmer than in recent months.

Imogen shared the snap on Twitter pointing towards her slim legs with the hashtag ‘#thighgap’.

She wrote: "GYM & @MuscleFoodUK combined - Results showing already #Thighgap #mealprep #Recommend."

One fan responded: “Not good. Can't understand the fascination with having a thigh gap. Not a good look and a turn off to be honest.”

Another wrote: “Looking a bit too skinny. Don't lose anymore.”

Like most new mums, Imogen struggled to shed the last stubborn pounds following the birth of her 2-year-old daughter Ariana.

The 32-year-old told a UK magazine: "I think when you have a baby, a lot of mums get into a rut, where they feel they can't go out and be themselves again.”

Imogen added: "I put on three stone, and that's a lot to lose. There were times when I thought, 'How am I ever going to lose this?' But it just goes to show you can do it."
