X Factor star Jesy Nelson has shed more than a stone in weight in the lead up to this weekend's live tour.
Having hired a personal trainer, the Little Mix singer is hoping to slim down even further, with friends claiming she hopes to lose as much as two more stone before the summer.
"There have been tears and pain in the gym since Christmas - but Jesy is delighted with her new figure," a source tells Closer this week.
"She'd have never have dreamed of putting on a skimpy bikini before now."
But while some fans of the group have been critical of Jesy's weight loss, the source insisted that the change had done her the world of good.
They revealed: "Jesy has a new confidence. She feels she can stand proudly next to the rest of Little mix."
Jesy's X Factor tour makeover has also seen a new red hair style, joining her Little Mix bandmates Jade and Leigh-Anne.
The group will be headlining the X Factor 2012 live tour, which starts in Manchester tomorrow.
