The 'Mean Girls' star - who also said looking at trees was "fun" - came out with the bizarre statement during a recent interview reports Female First.

She explained to In Style magazine: "I'm happiest when I'm just sitting.

"I recently went to a redwood forest with a friend and went on a hike. It was the most fun I've ever had."

Lindsay, who is renowned for her partying lifestyle, also revealed that she knows she needs balance in her life.

She said: "I learned to have a lot of responsibilities at a very young age, whether in my personal life at home with my family or simply having to be on set.

"I work longer hours than my friends' parents do."
