From Ananova:
Sigourney Weaver has revealed she lived in a tree when she was a student.

The 54-year-old actress, who was studying at Stanford University at the time, said she and her boyfriend moved out of college accommodation to set up home in the tree.

She told German magazine Gala: "We didn't have a tree house, it was just a platform."

Weaver also revealed she used to dress in costume to go to lectures: "I sometimes dressed as an elf, but also as a tiger," she said.
