Earlier this week friends close to the couple confirmed the reunion, revealing that the lovebirds were "100 per cent back together".
"Jamie is back in the family home and he's looking forward to seeing Kym when she returns," an insider told The Mirror. "They are 100 per cent back together and have decided to make a real go of things. Despite their rows they love each other dearly."
Kym, 37, had been on holiday with her two children from a previous relationship, but was spotted back in London in time to attend the Manchester United game on Monday. The Coronation Street actress has a two-year-old daughter Polly with her husband Jamie.
Kym and Jamie first sparked rumours that their marriage was on the rocks after a series of heated arguments and speculation that they had put their Greater Manchester family house up for sale.
While Kym stayed in Manchester with her children, Jamie spent a few weeks apart from his wife, busy filming in London for his new EastEnders role.
It seems the soap couple's trial separation has worked wonders though, as Kym and Jamie look to be very much back in love.
