Julie Leach has quit her job. I know, you're shocked! The 50-year-old woman who worked as an overnight supervisor at a fiberglass factory in West Michigan said it was an easy decision to quit a "nasty, dirty job."

"I quit automatically. I was done," she said, laughing, at a news conference Tuesday.

Leach tells NBC that she found out she had the winning ticket, worth $310.5 million, while eating a cheeseburger value meal from McDonald's.

She and her partner of 36 years say they plan to buy a large plot of land, and build homes for their three children. They also plan to pay off their mortgage, and cars. Although she and Vaughn Avery have always been happy without getting married, she joked that if he proposes, he'll have to sign a prenup.
