When she was younger, actress Diane Kruger was under the impression that being beautiful meant being skinny.

The 36-year-old actress, who has been in a relationship with actor Joshua Jackson for nine years, shared that her old outlook was "stupid" and her stance changed when she turned 30, reports femalefirst.co.uk.

"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,` Io Donna magazine quoted Kruger as saying.

Asked when she feels beautiful, the `Inglourious Basterds` actress said : "When the person I love tells me, 'I love you'. I'm not joking, it's true.`
