Jessie, 37, split from the ex-boxer, 25, - said to be over their age gap.
But the pair have got back together weeks after mum-of-one Jessie shed two stone in six weeks, dropping from size 16 to size 10. A source close to the couple said: "They stayed in touch and over time realised the old spark was still there.
"Losing weight gave Jess a huge confidence boost which Tommy found very sexy. They're enjoying being a couple again."
