Gillian Bayford said she didn't believe her husband when he announced they had won more than £148 million in the lottery.
She was putting her son to bed when her husband Adrian told her about the win:
I said, I will look later. I am busy. So I got my son settled. I looked on the internet, I looked at the ticket, and then we just looked at each other and giggled a lot.
Adrian and Gillian Bayford from Haverhill in Suffolk won more than £148.6 million in the EuroMillions jackpot on Friday.
The huge prize is the second biggest in lottery history.
