Binky Felstead went on a fitness kick to become the new face of Bluebella lingerie.

The 23-year-old 'Made in Chelsea' star was chosen by the provocative lingerie brand because she is a ''real girl's girl'', but she admits she still felt compelled to hit the gym before shooting the campaign.

Binky, real name Alexandra, lost a stone during a six week of intense training - going down from 10st 2lbs to 9st 2lbs - and the results are evident in the new photos.

She said: ''I was really thrilled to be asked to be the face of Bluebella lingerie but I was seriously worried that I would not look good in the photos.

''There's nowhere to hide the bits you don't like when you are wearing just a bra and knickers. So I knew I had to get on a serious fitness kick.''

Binky used to feel self-conscious and under-dressed compared to her E4 co-stars Millie Mackintosh and Rosie Fortescue when they first started filming the show.

She joked: ''Mille and the other girls wore soft and silky negligees and amazing skimpy underwear sets and I turned up in my ... ancient tracksuit bottoms.

''It hit me then that maybe I should start caring more about how I looked. I think I had lost touch with my appearance a bit.''

Despite admitting she may need to ''up [her] game'', Binky looks incredible in the Bluebella lingerie shoot which showcases their gorgeous new Tatiana range, costing £38.

Binky said: ''The beauty of Bluebella is that at less than £50 for a set ... you can look absolutely stunning without maxing your Amex.''

She stressed that there was no pressure from the underwear retailer to lose the weight as they cater from sizes 6 to 26.

Emily Bendell, Bluebella's founder, chose Binky as the face of the brand because she has a fabulous personality as well as her good looks, adding, ''Binky is a real girl's girl.''
