It’s believed the 5ft 2 singer, who was a size 14 before Christmas has lost the weight thanks to a strict diet along with three-hour gym sessions.
She’s also replaced junk food with porridge, grilled chicken, salad and fruit.
Jesy has been in the gym five days a week, with workouts including 90 minutes of circuits and weights, followed by at least 30 minutes on the treadmill. She’s also replaced junk food with porridge, grilled chicken, salad and fruit.
The comments really got to me. I knew I’d get nasty stuff said about my weight from the start
A source adds: “Jesy has a new confidence. She feels she can stand proudly next to the rest of Little Mix.”
Addressing the cruel taunts she suffered during her time on the X Factor, Jesy previously admitted:
'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.'
We think she looks fab! What do you think?
