Charlotte Crosby shows off her toned figure in bodycon dress... as former Geordie Shore co-star Sophie Kasaei also looks noticeably slimmer

She's blown all other celebrity slim-downs out of the water after her fitness DVD became the biggest-seller in 15 years.

And Charlotte Crosby continued to parade her newly-toned frame as she enjoyed a big night out in Newcastle on Saturday to celebrate a friend's birthday.

But it wasn't just Charlotte who was displaying a super slim figure since her BFF and former Geordie Shore co-star Sophie Kasaei was looking tinier than ever.

The star, who was axed from the MTV series in 2013, looked fantastic in a beige dress that hugged her every curve.

The girls have been swapping diet tips and working out together, with Charlotte favouring healthy eating after years of watching her weight yo-yo due to her party lifestyle, and Sophie following the Muscle Foods meal plan.

The 24-year-old reality star looked glamorous in a bodycon khaki dress from InTheStyle, which boasted a high neck and cut-outs on the back.

She paired her simple look with strappy sandals and a brown suede clutch bag as the girls partied the night away at Bonbar, before moving onto Tup Tup Palace.

Charlotte wore her long blonde extension in waves and went heavy on the bronzer to accentuate her tan.

The Geordie lass has been busy promoting her workout DVD 3-Minute Belly Blitz, which is said to have garnered more in sales than Disney hit Frozen.

The star's transformation has seen her go from 11 stone to 8 and a half stone, dropping four dress sizes, and she claims she has never been happier with her figure.

But Charlotte says the pressure is higher than ever to stay slim because the public are willing her to fail.

'I do feel it and I don't like it. Everyone is waiting for me to slip up and put it back on', she told The Sun's Fabulous magazine.
