The drawing was held Saturday, but Royal said she and her husband didn't give the ticket any thought until their drive home on Monday.
The couple checked the ticket and had to pull over to the side of the road when they realized they had won $1 million.
"We're still in shock," Royal said. "And here I am driving in all of Labor Day traffic."
Royal said her prize money will go toward paying off bills, making investments and taking a honeymoon.
