The Transformers actress has previously admitted she had a frosty relationship with Lindsay Lohan during filming of Disney hit Confessions of a Teenage Drama Queen.
And she admits she rarely becomes pals with her fellow female leads - insisting she always prefers the company of men.
Fox tells Britain's Heat magazine, "I actually only had one girlfriend growing up.
"Most of my friends were boys. I was such a tomboy. I always enjoyed doing guy things. So I really didn't get along with the girls in that aspect. My one girlfriend lives in Florida and she works in a mall. She's the furthest thing from an actress.".
