Margot Robbie is driven "insane" by her own thoughts.

The 'Suicide Squad' star hates to be alone with her thoughts and tries to do everything with her other half Tom Ackerley or her friends.

She said: "I never do anything on my own. I don't see the purpose of doing anything if I don't do it with my friends. I go mental when I am on my own; my thoughts are so loud it drives me insane."

Meanwhile, Margot previously revealed she is an expert in saving money.

She said: “Saving money is my area of expertise. It's a good skill to have for reallocating funds in a film budget.”
