The Little Mix star has previously insisted that she was happy with her curves, but in a new picture the 22-year-old seems to be focused on getting into shape.

After a two hour long workout Jesy is seen collapsed on the floor wearing just a tiny pair of shorts and a sports bra, revealing the full effects of her weight loss.

She wrote alongside the picture: ‘LA gym buddies… Me and @SamCoxy after a sweaty 2 hour work out! Jesy xxx #WorkHardPlayHard.’

Jesy’s manager appears to be providing some heavy motivation for the brunette beauty, and LA has likely to have had an effect on the young singer- encouraging the likes of Rita Ora and other celebs to get fit and healthy in the past.

Celebrity trainer Nicki Waterman has revealed to a magazine that there is now extra pressure on the girls to look perfect as they try to break America.

Jesy is said to have lost just over two stone by engaging in more abdominal work and working out three or four days a week.

Her diet and fitness regimes in the past were said to consist of circuit and weight training, alongside a diet of porridge, grilled chicken, salad and fruit.

Earlier this year a source revealed that Jesy had a new confidence and that ‘she can stand proudly next to the rest of Little Mix’.

During the band’s time on The X Factor Jesy admitted to being the victim of cruel taunts about her weight:

'When you’ve got your own insecurities and then people… write them on websites for everyone to see, it just makes you feel really rubbish.'

'Obviously, I know I’m a lot bigger [than the other girls]. The comments really got to me. I knew I’d get nasty stuff said about my weight from the start.’

'But it’s not until you actually see it that it hits you. I thought I’d be alright and then I saw it and just burst out crying.'

Judging by this recent picture and Jesy’s increasingly daring wardrobe choices, we hope that that her new found confidence is here to stay!
