See the reality star's changing shape...

When it comes to her weight, Charlotte Crosby knows that she’s fluctuated over the years.

As our gallery reveals, the Geordie Shore star was a svelte 9st when she first came to fame in 2011.

In our first picture – taken that July – she looks healthy while promoting the programme’s first series with co-stars Vicky Pattison and Sophie Kasaei in London.

She’s happy to show off her tanned figure in a skimpy monochrome midi. However, a few months later in January 2012 she seems shyer in a baggy dress at the BBC Radio 1 studios.

In May 2012, Charlotte cuts a slim shape at the London premiere of The Dictator. She displays her super-lean frame in a tight bandeau dress.

The pretty Sunderland girl is just as confident in a plunging black top in January 2013.

But by May 2013, it appears she’s no longer happy with her weight. Charlotte Crosby snaps a picture of a gym machine for her Instagram page and tells fans her work-out ‘better f*kin pay off’.

While Charlotte continues to don sexy outfits, she shares a photo of a healthy salad in June 2013 and admits two months later that she’s ‘put on so much weight she wants surgery’.

Entering the Celebrity Big Brother house a few days later, she’s crept up to 10st 5lb and says she’s at ‘rock bottom’.

After being announced as the winner of the Channel 5 show, she sticks to a healthy diet and says she’s noticed her boobs getting smaller.

Unfortunately for Charlotte Crosby, weight continues to be an issue. In May 2014, she opens up about how she ‘absolutely hates her body’ and hasn’t been to the gym for six months.

This time, Charlotte proves she’s really dedicated to changing her lifestyle when she’s spotted exercising with a personal trainer and by September 2014 she’s looking noticeably slimmer.

In October 2014, Charlotte shows how far she’s come by uploading a gorgeous Instagram shot of herself in a skimpy figure-hugging piece for cast mate Holly Hagan’s book launch.
