The Beverly Hills, 90210 star was so shocked to find her winning numbers printed in the local newspaper, she quit her job thinking she had just struck it rich.
However, gullible Doherty reveals her happiness quickly faded when she found out it was just a prank.
She recalls, "Every once and while when the lotto was really big, the cast would all go in and buy everybody on the crew and ourselves lottery tickets... The next day comes around (so)... I grab my lotto ticket, go back to the make-up trailer, sit there, look through the newspaper - and I've won. It was like $42-52 million (£26-33 million), somewhere in that range.
"I jump up - I'm screaming hysterically - I run out of the make-up trailer, I run to my trailer, I gather up all my stuff, I run to my car, jump in, put it in drive, and start peeling out of the lot.
"(The cast and crew) come running after my car screaming, I stop really quick, and I'm like, 'What?' And they're like, 'Where are you going?' and I'm like, 'I won the lottery, I quit!' They had to tell me that I did not win the lottery and I was still broke and I still had to work. I actually cried hysterically, I had tears pouring down my face."
