Because Titanic had a really gruelling filming schedule, the stars had to use the bathroom in shifts, but Kate Winslet revealed that she just peed in the water tank from time to time.

We all know that the chihuahua wasn’t mauling Amy Poehler’s actual chest in Mean Girls, so what was going on there? Well, Amy had a piece of cocktail sausage pinned inside her bra, and the rest is history.
