Rachel McAdams may make a stunning cover girl for Glamour magazine next month -- but her life wasn't always so glamorous.

The 33-year-old Canadian actress describes her past working at McDonald's in the mag's February issue.

"Yeah, for a good three years. My sister and brother worked there. My sister was my manager," says Rachel. 

"It was a great place to work, but I had a little bit of an OCD thing with hand washing and just didn't have time. They were like, "Hey, the drive-through's backing up. Stop washing your hands," she continues. "I was not a great employee; I broke the orange juice machine one day."

McAdams is only one of many celebs who have worked at the Golden Arches though -- check out the gallery above to see who else used to get fast food paychecks, plus other embarrassing first jobs!
