I thought beautiful meant skinny: Diane Kruger

Actress Diane Kruger has revealed she used to think being beautiful "meant being skinny" but changed her outlook when she turned 30.

The 36-year-old actress, who is in a relationship with actor Joshua Jackson, admits her old outlook was "stupid," reported Female First.

"When I was younger, being beautiful meant being skinny; I was a model, so you can imagine how hard it was to stay in shape.

"But when I turned 30, I realised how stupid I was for believing that. I think you're beautiful when you're smart and beauty is something you need to achieve.
