A mum-of-two has become wealthier than Beyonce and Taylor Swift  after she scooped $758.7 million, the largest single win in American lottery history.

After realising she had won, Mavis Wanczyk, who beat odds of one-in-292.2 million, immediately called her work to say she would not be returning.

The 53-year-old, hospital cleric from Chicopee, Massachusetts, found out about her win while on what turned out to be her last night shift at a hospital where she had been for more than 30 years.

Mavis said she was with her colleague, Rob, when she checked her numbers.

She explained: “And he’s reading these numbers and I pull mine out and I go ‘hey, I have that …’ and he goes ‘let me see that ticket,’ he goes, ‘you just won.’” 

Mavis, the mother of a 31-year-old daughter and a 26-year-old son, said she wasn’t able to drive because she was so stunned.

 “I couldn’t do anything so he (Rob) followed me to make sure I made it home safely,’ she added.

When asked what she wants to do with all the money she has won, she said, “The first thing I want to do is just sit back and relax and I had a pipe dream and my pipe dream has finally come true, I wanted to retire in 12 (years) and it came early.

The shop owner, Bob Bolduc, collected $50,000 for selling the winning ticket and is planning to give the money to charity.

Mavis will now have to decide whether to take a lump sum or have her winnings paid out over 30 years.

If she chooses the quick cash she will receive about $480.5 million as wins in America, are taxed.

According to Forbes report, Beyonce’s estimated net worth is $350 million while that of Taylor Swift is $280 million.
