The partner of £61 million winner Sonia Davies, Keith Reynolds, split up with Mandy Reynolds two years ago after a 20-year marriage. It's been described as an amicable divorce.
Mandy now rents a modest home on an estate in Gloucester, but says she isn't envious of her ex's good luck.
"It is his money and he can do what he wants with it," she tells the Daily Mail.
"There is no bitterness on my part at all. We still get on well for the sake of the children and that's is all there is to it. I have not spoken to Keith about it but I have spoken to my daughters and they were thrilled."
Meanwhile, according to Metro, another ex is ruing the day he split up with one of the winners. Dan White, 21, broke up with Courtney Davies, 19, last year.
"All my mates are savaging me about this – the first I knew of their win was my phone going nuts," he tells the paper.
"The boys were all sending me links and jokey snapchats asking if I was gutted."
The Davies family scooped £61 million on Friday's Euromillions lottery, right after discovering that Sonia's cancer treatment had been successful.
They are believed to be splitting the win six ways, with around £12 million each going to Sonia Davies, 53, her partner Keith Reynolds, 55, daughters Stephanie, 23, and Courtney, 19, and Stephanie's boyfriend Steve Powell, 30.
In this case, there's clearly no ill-feeling from those that aren't getting a share.
However, in the past winners have found themselves besieged by exes desperate to nab a portion of the win.
Last year, for example, a Chinese man won £463,890 on the lottery and immediately decided to divorce his wife, without telling her about the win. However, she found out and successfully sued him for half the cash.
Earlier this year, a lottery winner's ex-partner successfully sued for a percentage of her $1 million win on the grounds that he'd given her the cash to buy the ticket.
However, she appears to have run through the money pretty quickly, filing for bankruptcy a few months later - without paying her ex.
